So, I have a problem with primefaces, I'm trying have a button that reset a panel but that button just don't work, here's the code.

The parent template has a form defyned in it.
I'm stuck in it so any tip will help, thank.
The most common reasons for an UICommand to not work are explained here: commandButton/commandLink/ajax action/listener method not invoked or input value not updated
From your given code, your case seems to fall in case 1: the components may not be inside a <h:form> component. Make sure in your template file you have a structure like this:
<h:form>
<ui:insert name="corpo" />
</h:form>
But note that this is not a good approach because is like having a god form in your page. It will be better if in your template file you have the <ui:insert name="corpo" /> without being inside any form and start defining the <h:form> inside your page. To give an example (based on your posted Facelets code):
<h:form>
<p:dataTable id="dataTable" var="fonte" value="#{ElaboracaoOrcamentariaControl.dotacao.fontes}">
<p:column headerText="Fonte">
<h:outputText value="#{fonte.fonte.codigo}" />
</p:column>
<p:column headerText="Descrição da fonte de recurso">
<h:outputText value="#{fonte.fonte.descricao}" />
</p:column>
<p:column headerText="Valor">
<h:outputText value="#{fonte.valor}" />
</p:column>
<p:column headerText="Excluir">
<p:commandButton id="selectButton" update=":form:display" immediate="true" icon="ui-icon-search" title="View" process="#this">
</p:commandButton>
</p:column>
</p:dataTable>
</h:form>

I have 3 dropdowns, the second has to be loaded based on the selected option of the first. And the third based on the selected option of the second.
This is the page:
<h:panelGrid columns="2" cellpadding="5">
<p:outputLabel value="Empresa:" for="selectCompany" />
<p:selectOneMenu id="selectCompany" value="#{dropdownBean.company}"
converter="entityConverter" effect="fade" effectSpeed="200"
var="company">
<p:ajax process="#this" event="change"
update="selectBranch, selectVendor" />
<f:selectItems value="#{dropdownBean.companies}" var="companyItem"
itemLabel="#{companyItem.corporateName}" itemValue="#{companyItem}" />
<p:column>
<h:outputText value="#{company.corporateName}" />
</p:column>
</p:selectOneMenu>
</h:panelGrid>
<h:panelGrid columns="2" cellpadding="5">
<p:outputLabel value="Surcursal:" for="#selectBranch" />
<p:selectOneMenu id="#selectBranch" value="#{dropdownBean.branch}"
converter="entityConverter" effect="fade" effectSpeed="200"
var="branch">
<p:ajax process="#this" event="change" update="#selectVendor" />
<f:selectItem itemLabel="SELECCIONE SUCURSAL" itemValue=""
noSelectionOption="true" />
<f:selectItems value="#{dropdownBean.branches}" var="branchItem"
itemLabel="#{branchItem.branchName}" itemValue="#{branchItem}" />
<p:column>
<h:outputText value="#{branch.branchName}" />
</p:column>
</p:selectOneMenu>
</h:panelGrid>
<h:panelGrid columns="2" cellpadding="5">
<p:outputLabel value="Vendedor: " for="#selectVendor" />
<p:selectOneMenu id="#selectVendor" value="#{dropdownBean.vendor}"
converter="entityConverter" effect="fade" effectSpeed="200"
var="vendor">
<f:selectItem itemLabel="SELECCIONE VENDEDOR" itemValue=""
noSelectionOption="true" />
<f:selectItems value="#{dropdownBean.vendors}" var="vendorItem"
itemLabel="#{vendorItem.vendorName}" itemValue="#{vendorItem}" />
<p:column>
<h:outputText value="#{vendor.vendorName}" />
</p:column>
</p:selectOneMenu>
</h:panelGrid>
And the backbean:
#ManagedBean
public class DropdownBean {
#Inject
private CompanyBC companyBC;
#Inject
private BranchBC branchBC;
#Inject
private VendorBC vendorBC;
private V_Companies company;
private V_Branches branch;
private V_Vendors vendor;
private List<V_Companies> companies;
private List<V_Branches> branches;
private List<V_Vendors> vendors;
#PostConstruct
public void allCompanies() {
companies = companyBC.allCompanies();
}
public List<V_Companies> getCompanies() {
return companies;
}
public void setCompanies(List<V_Companies> companies) {
this.companies = companies;
}
public List<V_Branches> getBranches() {
if(company!=null)
branches = branchBC.allCompanyBranches(company.getCompanyId());
return branches;
}
public void setBranches(List<V_Branches> branches) {
this.branches = branches;
}
public List<V_Vendors> getVendors() {
if(company!=null && branch!=null)
vendors = vendorBC.allBranchVendors(company.getCompanyId(), branch.getBranchId());
return vendors;
}
public void setVendors(List<V_Vendors> vendors) {
this.vendors = vendors;
}
public V_Companies getCompany() {
return company;
}
public void setCompany(V_Companies company) {
this.company = company;
}
public V_Branches getBranch() {
return branch;
}
public void setBranch(V_Branches branch) {
this.branch = branch;
}
public V_Vendors getVendor() {
return vendor;
}
public void setVendor(V_Vendors vendor) {
this.vendor = vendor;
}
}
The first two dropdowns work great but the last one does not. Apparently cannot be more than one p:ajax for the same event or something like that. Any suggestions please?
adding a listener worked:
<p:ajax process="#this" listener="#{userEditMB.onBranchChange}" event="change" update="selectVendor" />
public void onBranchChange(AjaxBehaviorEvent event) {
setBranch((V_Branches) ((UIOutput) event.getSource()).getValue());
vendors = vendorBC.allBranchVendors(getBranch().getCompanyId(),
getBranch().getBranchId());
}
I tried listener before but passing the Id's as parameters. Passing AjaxBehaviorEvent and casting to the object was the answer for me. I hope helps someone
Thanks!
I want to capture selected text from inputTextArea on ajax dblclick or select event.How can I do this ?
The code below selects everything in the text area (which I don't want). Thank you very much.
<h:form id="form">
<p:panel header="Select Text">
<h:panelGrid columns="3" cellpadding="5">
<h:outputText value="Text: " />
<p:inputTextarea id="textarea"
value="#{selectedTextBean.selectedText}">
<p:ajax event="select" update="selectedText" />
</p:inputTextarea>
<h:outputText id="selectedText"
value="#{selectedTextBean.selectedText}" />
</h:panelGrid>
</p:panel>
</h:form>
Here is SelectedTextBean
#ManagedBean
#ViewScoped
public class SelectedTextBean {
public SelectedTextBean() {
}
private String selectedText;
public String getSelectedText() {
return selectedText;
}
public void setSelectedText(String selectedText) {
this.selectedText = selectedText;
}
}
You can use this plugin jquery-textrange.
xhtml
<p:inputTextarea onselect="setSelectedText()" />
<p:remoteCommand name="setSelectedTextCommand"
actionListener="#{mainBean.setSelectedText()}"
update="currentSelectedText" />
Selected Text is:
<h:outputText value="#{mainBean.selectedTextInArea}"
id="currentSelectedText" />
<h:outputScript library="js" name="jquery-textrange.js" />
<script>
function setSelectedText() {
var range = $('.ui-inputtextarea').textrange();// general selector
setSelectedTextCommand([{name: 'selectedText', value: range.text}]);
}
</script>
Bean
private String selectedTextInArea;
public void setSelectedText() {
FacesContext context = FacesContext.getCurrentInstance();
Map map = context.getExternalContext().getRequestParameterMap();
selectedTextInArea = (String) map.get("selectedText");
}
public String getSelectedTextInArea() {
return selectedTextInArea;
}
public void setSelectedTextInArea(String selectedTextInArea) {
this.selectedTextInArea = selectedTextInArea;
}
And Here's a live demo on Primefaces TextArea Selection, and on github.
You can do that sending a parameter to a remote command as follows:
The View
<h:form id="form">
<p:panel header="Select Text">
<h:panelGrid columns="3" cellpadding="5">
<h:outputText value="Text: " />
<h:panelGroup>
<p:inputTextarea id="textarea"
value="#{selectedTextBean.selectedText}" onselect="processSelection();" />
<p:remoteCommand name="sendSelection" actionListener="#{selectedTextBean.onSelect}" update="selectedText" process="#this" />
</h:panelGroup>
<h:outputText id="selectedText"
value="#{selectedTextBean.selectedText}" />
</h:panelGrid>
</p:panel>
</h:form>
<script>
function processSelection() {
var selectedText = (!!document.getSelection) ? document.getSelection() :
(!!window.getSelection) ? window.getSelection() :
document.selection.createRange().text;
sendSelection([{name: 'selectedText', value: selectedText}]);
}
</script>
Note that the text selection changes depending on the browser.
The Bean
import java.io.Serializable;
import java.util.Map;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
import javax.faces.context.FacesContext;
#ManagedBean
#ViewScoped
public class SelectedTextBean implements Serializable {
public SelectedTextBean() {
}
private String selectedText;
public void onSelect() {
FacesContext context = FacesContext.getCurrentInstance();
Map map = context.getExternalContext().getRequestParameterMap();
selectedText = (String) map.get("selectedText");
}
public String getSelectedText() {
return selectedText;
}
public void setSelectedText(String selectedText) {
this.selectedText = selectedText;
}
}
In short, if a component has been updated by Ajax, it can not launch new events Ajax
I have three h:selectOneMenu: A, B and C.
When I fire change event in A, then update the B h:selectOneMenu.
When I fire change event in B, then update the C h:selectOneMenu.
The problem is that when the content of B h:selectOneMenu is updated, the ajax in B don't work and C never can't be updated.
<h:selectOneMenu id="A" value="#{paqueteBean.mes}" label="a">
<f:selectItem itemLabel="Seleccione..." itemValue="" />
<f:selectItem itemLabel="Enero" itemValue="ENERO" />
<f:selectItem itemLabel="Febrero" itemValue="FEBRERO" />
<f:ajax listener="#{paqueteBean.changeMes}" render="B" />
</h:selectOneMenu>
<h:selectOneMenu id="B" value="#{paqueteBean.origen}" label="b">
<f:selectItem itemLabel="Seleccione..." itemValue="" />
<f:selectItems value="#{paqueteBean.origenes}" />
<f:ajax listener="#{paqueteBean.changeOrigen}" render="C"/>
</h:selectOneMenu>
<h:selectOneMenu id="C" value="#{paqueteBean.zona}" label="c">
<f:selectItem itemLabel="Seleccione..." itemValue="" />
<f:selectItems value="#{paqueteBean.zonas}" />
</h:selectOneMenu>
The ajax response is good, but simply don't work after the update:
<?xml version='1.0' encoding='UTF-8'?>
<partial-response id="j_id1"><changes><update id="B"><![CDATA[<select id="B" name="b" size="1" onchange="mojarra.ab(this,event,'valueChange','#this','C')"> <option value="">Seleccione...</option>
<option value="BUE">Ezeiza o Aeroparque</option>
</select>]]></update><update id="j_id1:javax.faces.ViewState:0"><![CDATA[-2984590031183218074:6198891110668113457]]></update></changes></partial-response>
UPDATE!
With PrimeFaces I have the same behavior:
<h:form id="filtro">
<p:selectOneMenu id="A" value="#{paqueteBean.mes}">
<f:selectItem itemLabel="Seleccione..." itemValue="" />
<f:selectItem itemLabel="Enero" itemValue="ENERO" />
<f:selectItem itemLabel="Febrero" itemValue="FEBRERO" />
<f:selectItem itemLabel="Marzo" itemValue="MARZO" />
<p:ajax listener="#{paqueteBean.changeMes}" update="B" />
</p:selectOneMenu>
<p:selectOneMenu id="B" value="#{paqueteBean.origen}"
disabled="#{empty paqueteBean.mes}">
<f:selectItem itemLabel="Seleccione..." itemValue="" />
<f:selectItems value="#{paqueteBean.origenes}" />
<p:ajax listener="#{paqueteBean.changeOrigen}" update="C"
process="origen mesSalida" />
</p:selectOneMenu>
<p:selectOneMenu id="C" value="#{paqueteBean.zona}"
disabled="#{empty paqueteBean.mes or empty paqueteBean.origen}">
<f:selectItem itemLabel="Seleccione..." itemValue="" />
<f:selectItems value="#{paqueteBean.zonas}" />
</p:selectOneMenu>
When I change some A values, the method in backing bean is fired, but when I change some B value, the method in backing bean is not fired.
The most strange is that for items that existed in B before the ajax update, the backing bean is called.
Backing Bean, nothing special:
public void changeMes(){
logger.debug("en changeMes el Mes es: " + this.mes);
this.origenes = new HashMap<String, String>();
this.origenes.put("Ezeiza o Aeroparque", "BUE");
}
public void changeOrigen(){
logger.debug("Mes: " + this.mes);
logger.debug("Origen" + this.origen);
this.zonas = new HashMap<String, String>();
this.zonas.put("Argentina", "AR");
this.zonas.put("Brasil", "BR");
}
public void changeZona(){
logger.debug("Mes: " + this.mes);
logger.debug("Origen" + this.origen);
logger.debug("Zona" + this.zona);
this.destinos = new HashMap<>();
this.destinos.put("Mar del Plata", "MDQ");
this.destinos.put("Punta Lara", "LTA");
}
UPDATE:
here is a working example:

Instead of using <f:ajax/> you can also use the PrimeFaces-Ajax-Element <p:ajax> which offers you a update-attribute:
<p:ajax update="elementID"/>
Another possibility I can recommend: Have you tried to put your SelectOneMenus in a <h:form>-Element? It looks like you didn't use a form. Do so, then you can always update the form in order to make the menues change. Worked good for me at my projects.
I had the same mistake.
For the second selectonemenu i miss a setter.
In your code it was the setter for myBean.selectedB.
Check all your getter and setter. Maybe there is the problem
I am having problems with the site I am creating. I am new to Faces 2.0 and was only using JSP and now shifting to Faces 2.0. I have a page that adds and deletes a location Zip Code. The edit part works but the add part, I am having an error:
PropertyNotFoundException, Target Unreachable, 'null' returned null.
on following value:
value="#{zipCodeMaintennanceBean.selectedZipCode.description}"
I dont know why it does not work because the edit part works and they use the same ManagedBean.
I am using Spring 3.1.3 With Hibernate and PrimeFaces 3.5. I hope someone answers my question as I dont know how to solve this.
I suspect that whenever I click the button, a new object is being created as I am using a #RequestScoped annotation.
I tried to from instantiating the entity class on #PostConstruct Method, even instantiating the entity on the declaration and setting an empty string on description and nothing works.
It doesnt get to call save() method and seems to get stuck on the Update Model Values Phase

Thank you in advance.
In your dataTable you are using the same variable for row selection.
selectionMode="single" selection="#{zipCodeMaintennanceBean.selectedZipCode}"
When no row is selected the selectedZipCode attribute will be null and you will continue to get an Exception.
You could simply use another instance of TblZipcodes for the addDialog.
PS: Some time ago someone reported a bug when giving the same name to id and widgetVar as you did in addDialog, check if this is a problem in version 3.5.
I am migrating an JSP/Servlets website to JSF and am having difficulty in implementing some of the more interesting abilities of JSF.

I have tried a number of different strategies, and have read a fair number of very detailed explanations of this process in other StackOverflow threads (Thank you, BalusC!), but have still been unable to actually invoke the action listener.
My Environment is as follows:
Java 1.6
Eclipse Kepler (originally Juno)
GlassFish 3.1.2
PrimeFaces 3.5.0
From a presentation perspective, the XHTML displays correctly. The <p:dataTable> element is rendered just like the documentation and examples indicate, but when I attempt to delete a a row, the listener is never invoked.
I have tried changing the update name several times. Currently, the value of the update parameter is profile:docListForm:docListTable.
Other posts seem to indicate that there was a problem with <p:commandButton> from within a <p:accordianPanel>, but that was for a previous version of PrimeFaces (3.2).
I have tried moving the <p:commandButton> outside the <p:dataTable> and also on each row, yet the behavior does not change.
If your Listener does not trigger try this, it work fine in p:tables
<p:column id="delete" headerText="Action" width="65">
<h:commandLink value="Delete"
action="#{documents.deleteReference(current.docNo,animals.aifNo,current.group)}" ajax="false" />
</p:column>
And in your documents bean:
public void deleteReference(String docNo, String aifNo, String group)
You can actually pass the 2 string that you eventually cast as int but as Integer wrapper in the method not the primitive.
Cheers,

Try to add ajax="false" attribute in commandbutton ,Something like this.
<p:commandButton value="Non-Ajax Submit" actionListener="#{pprBean.savePerson}"
ajax="false" />
Or use h:commandButton with ajax="false" here also .
In my application i got same issue plenty of time and i got answer few week back that issue with the page or code somewhere in the page or managed bean throwing exception or some logic going fail which is generating exception for JSF that is the main reason behind firing the event.It is JSF2 feature not to fire event if code or logic fail somewhere . May be this will help you
