I try to get the rowindex from the actual selected Column to unselect it with:
public void rowSelect(SelectEvent event) {
MyDataView selected = (MyDataView) event.getObject();
if (!selectedData.remove(selected)) {
selectedData.add(selected);
} else {
RequestContext.getCurrentInstance().execute("PF('datatTable').unselectRow(rowindex);");
}
}
}
I know it is easy to unselect a row with the UnselectEvent and press "crtl" but my Customers want to unselect a row with one click.
<p:dataTable widgetVar="datatTable" id="idDataTable" value="#{bean.dataview}" var="data" scrollable="true" scrollHeight="150"
rowSelectMode="add" selectionMode="multiple"
selection="#{sendGroupSmsSimple.selectedReceivers}" rowKey="#{bean.id}" filteredValue="#{data.filterData}" rowIndexVar="dataRowIndex">
<p:column id="recColumn" headerText="Name" filterBy="#{bean.fullname}" filterFunction="#{data.filterData}">
<h:outputText value="#{bean.fullname}"/>
</p:column>
<p:ajax event="rowSelect" listener="#{sendGroupSmsSimple.rowSelect}" process="#this" update="mainForm:updatePanel"/>
</p:dataTable>
I don't want to update my whole Form because I want the actual state of my scrollbar.
My actual Primefaces Version is 6.0.
Scope of my Bean is GroupedConversationScoped.
Thanks

The Primefaces table which will be filtered by different column attributes needs to have a summary row that will update its value as the user change the values in filters. Is there any way to do this?
Create a Column Group footer in the payments.xhtml:
<p:dataTable var="payments" value="#{testBean.payments}" filteredValue="#{testBean.filteredPayments}">
<p:column headerText="Payment status:" filterBy="#{payment.status}">
<h:outputText value="#{payment.status}"/>
</p:column>
<p:columnGroup type="footer">
<p:row>
<p:column colspan="6" headerText="Total: "/>
<p:column colspan="2" headerText="#{testBean.totalPaymentsSum}"/>
</p:row>
</p:columnGroup>
</p:dataTable/>
In the TestBean.java add a method as a getter to calculate the summary row:
List<Payment> payments;
List<Payment> filteredPayments;
public String getTotalPaymentsSum() {
int total = 0;
for(Payment payment : filteredPayments) {
total += payment.getAmount();
}
return new DecimalFormat("###,###.###").format(total);
}
For more filter option see the Datatable Filter showcase.
If you have a lot of data and you are using datatable Lazy loading, you can calculate the summary row in the load() or filter() method.
I have an input field and a table on page. Whenever a number in a field changes (ajax listener to change event) - I want number of rows to change accordingly.
I pointed the table to an Arraylist in a Backing bean, and play with its size.
But then when I edit a value in the table - and press enter, the table disappears, and reappears only when I change field value again.
As a bonus, in debug mode, I see that backing arraylist always have empty values.
Here goes the Bean code:
#ManagedBean(name = "bean")
#ViewScoped
public class TestBean {
private List<String> hostnames = new ArrayList<String>();
private int copiesQuantityJustCopy;
public int getCopiesQuantityJustCopy() {
return copiesQuantityJustCopy;
}
public void setCopiesQuantityJustCopy(int copiesQuantityJustCopy) {
this.copiesQuantityJustCopy = copiesQuantityJustCopy;
}
public List<String> getHostnames() {
return hostnames;
}
public void setHostnames(List<String> hostnames) {
this.hostnames = hostnames;
}
public void onUpdateCount() {
int hostnamesCount = hostnames.size();
System.out.println("delta = " + hostnamesCount + " - " + copiesQuantityJustCopy);
int delta = hostnamesCount - copiesQuantityJustCopy;
if (delta > 0)
for (int i = 1; i < delta; i++)
hostnames.remove(delta);
if (delta < 0)
for (int i = 0; i < -delta; i++)
hostnames.add("");
}
}
and the view code:
<h:form id="form1">
<p:inputMask mask="9?99" maxlength="3" placeHolder=" " value="#{bean.copiesQuantityJustCopy}">
<p:ajax event="change" listener="#{bean.onUpdateCount()}" update=":form1:hostnamesTable" />
</p:inputMask>
<p:outputPanel id="hostnamesTable" rendered="true">
<p:dataTable value="#{bean.hostnames}" var="hostname"
id="hostnames" editable="true" editMode="cell">
<p:ajax event="cellEdit" update=":form1:hostnamesTable" process="#this" />
<p:column>
<p:cellEditor>
<f:facet name="output">
<h:outputText value="#{hostname}" />
</f:facet>
<f:facet name="input">
<p:inputText value="#{hostname}" style="width:96%" />
</f:facet>
</p:cellEditor>
</p:column>
</p:dataTable>
</p:outputPanel>
</h:form>
I think my answer won't help #Anton, but it may be helpful to another "stackers" facing same problem.
My problem is similar (dataTable dissapears when cellEdit event is completed). In my case the cause was the table update performed by ajax. Since I realy don't need table update after listener firied I simply removed update attribute and now everything works good to me.
I have used column picklist to customize columns of table on page and I want to show dialog message (Atleast one column should be enabled) if user disables all the columns from picklist. That means user should keep atleast one column in enable box.
<p:dialog id="pickListDialog" header="Customize View"
widgetVar="dlg">
<h:panelGrid>
<p:pickList id="columnPickList"
value="#{Class_Name.columns}" var="col"
itemLabel="#{Class_Name.columnPickList.columnsDisplayMap.get(col)}"
itemValue="#{col}">
<f:facet name="sourceCaption">Disabled</f:facet>
<f:facet name="targetCaption">Enabled</f:facet>
</p:pickList>
<p:commandButton value="Submit"
actionListener="#{Class_Name.columnPickList.saveColumns}" onclick="return disableClick();"
ajax="false" />
</h:panelGrid>
</p:dialog>
Javascript method -
function disableClick(){
if (document.getElementById("form:columnPickList_target").value == ""){
alert("Please Select Atleast One Field");
return false;
}
}
Here I have used Javascript for this. But I want to do this by JSF .
can anyone please tell me ?
Case 1 : Using required attribute
<p:pickList id="columnPickList" required="true" requiredMessage="Atleast one column should be enabled"
value="#{Class_Name.columns}" var="col"
itemLabel="#{Class_Name.columnPickList.columnsDisplayMap.get(col)}"
itemValue="#{col}">
<f:facet name="sourceCaption">Disabled</f:facet>
<f:facet name="targetCaption">Enabled</f:facet>
</p:pickList>
Case 2 : Opening dialog from backing bean
public void saveColumns()
{
validateColumns();
//doSomthing
}
public void validateColumns() {
//check if picklist target is empty
if(columns.getTarget().size()==0)
{
//open dialog
message="Atleast one column should be enabled";
RequestContext.getCurrentInstance().execute("validationDialog.show()");
}
}
private String message; //getter and setter
dialog :
<p:dialog id="valid" widgetVar="validationDialog">
<p:outputLabel value="#{yourbean.message}" />
</dialog>
I'm new to JSF and in class we should just set up a little "Pizza-Service" with logins etc. On the Page where i want to prepare my Order as a user I've a data table (primeface data table) with 4 columns. The last one is for the number of pizza of the type in the current cell.
What I want: If I am typing in a Number i want to set up a current Order (works fine so far with ajax) in the same moment i just want to show the user the current price. This is the little thing that is not working.
When I am using the tag there is just nothing happening and if I am taking the tag I'm getting this mistake:
<f:ajax> contains an unknown id 'ausgabe' - cannot locate it in the context of the component menge
What I thought was take the ajax tag set up a function (take the current order) and render an output text where the calculated price is shown directly. I called those function in german so bestellungAufnehmen = takeOrder and preisBerechnen = calculatePrice.
Thanks if someone could help me!
Here is the xhtml:
<h:head>
<title>Facelet Title</title>
</h:head>
<h:body>
<h:form>
<p:dataTable id="table" var="pizza" value="#{model.getPizzen()}">
<p:column headerText="Nr">
<h:outputText value="#{pizza.nr}"/>
</p:column>
<p:column headerText="Artikel">
<h:outputText value="#{pizza.name}"/>
</p:column>
<p:column headerText="Preis">
<h:outputText value="#{pizza.preis}"/>
</p:column>
<p:column headerText ="Menge">
<h:inputText id="menge" value="#{bestellung.anzahl}">
<f:ajax event="keyup" render="ausgabe" listener="#{bestellung.bestellungAufnehmen(pizza)}"/>
</h:inputText>
</p:column>
</p:dataTable>
<h:outputLabel value="Zu Zahlen: "/>
<h:outputText id="ausgabe" value="#{bestellung.preisBerechnen()} €"/>
</h:form>
</h:body>
and here is the the Bean with those functions.
#Named
#SessionScoped
public class Bestellung implements Serializable {
private static int bstzaehler=0;
private int bstnr;
private Map<String,Bestellposten> posten;
private int anzahl;
public Bestellung(){
this.bstnr=++bstzaehler;
this.posten = new HashMap<>();
}
/**
* #return the bstnr
*/
public int getBstnr() {
return bstnr;
}
/**
* #param bstnr the bstnr to set
*/
public void setBstnr(int bstnr) {
this.bstnr = bstnr;
}
public void bestellungAufnehmen(Pizza pizza){
if(this.posten.containsKey(pizza.getName()) == false){
Bestellposten b = new Bestellposten(this.getAnzahl(), pizza);
this.posten.put(pizza.getName(),b);
} else {
if(this.getAnzahl() > 0 ){
Bestellposten tmp = this.posten.get(pizza.getName());
tmp.setMenge(this.getAnzahl());
} else {
this.posten.remove(pizza.getName());
}
}
System.out.println("groesse: "+posten.size());
System.out.println("akt preis: "+this.preisBerechnen());
}
/**
* #return the anzahl
*/
public int getAnzahl() {
return anzahl;
}
/**
* #param anzahl the anzahl to set
*/
public void setAnzahl(int anzahl) {
this.anzahl = anzahl;
}
public double preisBerechnen(){
double sum = 0.0;
for(String key : this.posten.keySet()){
Pizza tmp = this.posten.get(key).getPizza();
sum += tmp.getPreis() * this.posten.get(key).getMenge();
}
return sum;
}
}
Try giving the full qualified id for the component:
<h:form id="frmPizza">
<p:dataTable id="table" var="pizza" value="#{model.getPizzen()}">
<p:column headerText="Nr">
<h:outputText value="#{pizza.nr}"/>
</p:column>
<p:column headerText="Artikel">
<h:outputText value="#{pizza.name}"/>
</p:column>
<p:column headerText="Preis">
<h:outputText value="#{pizza.preis}"/>
</p:column>
<p:column headerText ="Menge">
<h:inputText id="menge" value="#{bestellung.anzahl}">
<f:ajax event="keyup" render=":frmPizza:ausgabe" listener="#{bestellung.bestellungAufnehmen(pizza)}"/>
</h:inputText>
</p:column>
</p:dataTable>
<h:outputLabel value="Zu Zahlen: "/>
<h:outputText id="ausgabe" value="#{bestellung.preisBerechnen()} €"/>
</h:form>
I think, you should use update attribute to update that outputText, like update=":FormId:ausgabe"
<f:ajax event="keyup"
render=":frmPizza:ausgabe"
listener="#{bestellung.bestellungAufnehmen(pizza)}"
update=":frmPizza:ausgabe" />
The solution of luiggi worked but i couldnt answer directly because of my "low-level" here.
Iam not on my computer right now but isnt "update" an attribute of p:ajax and not of f:ajax and is the same as render? but i will try it aswell later on.
thx!
I have a trinidad table with one column contains drop downs (select one choice) for each row and another column contains an input text for each row.
When a particular option is selected, the input becomes editable (else it remains read only).
The read only behaviour and the partial event are working perfectly as expected. The problem is whenever the input text is supposed to move from editable to read only, I still see the value previously entered when the input text was editable.
From here if I select another option (for which the input text would also be read only) the value goes away.
The JSP Code is as follows:
<tr:table emptyText="No Data" var="vo" autoSubmit="true" partialTriggers="accountType" value="#{testingBean.voList}" binding="#{testingBean.table}" width="50%">
<tr:column>
<f:facet name="header">
<tr:outputText value="Sl No" />
</f:facet>
<tr:outputText value="#{vo.slNo}" />
</tr:column>
<tr:column>
<f:facet name="header">
<tr:outputText value="Account Type" />
</f:facet>
<tr:selectOneChoice unselectedLabel="Select" id="accountType" value="#{vo.accountType}"
autoSubmit="true" immediate="true" valuePassThru="true"
valueChangeListener="#{testingAction.optionsChanged}">
<f:selectItems value="#{testingBean.options}" />
</tr:selectOneChoice>
</tr:column>
<tr:column>
<f:facet name="header">
<tr:outputText value="Other" />
</f:facet>
<tr:inputText value="#{vo.otherType}"
partialTriggers="accountType"
readOnly="#{vo.readOnlyFlag}"></tr:inputText>
</tr:column>
</tr:table>
The code for the valueChangeListener is as follows:
public void optionsChanged(ValueChangeEvent vce) {
try {
System.out.println("Inside Method");
testingBean = (TestingBean) FacesContext.getCurrentInstance()
.getExternalContext().getSessionMap().get("testingBean");
ArrayList<TableRowVO> list = testingBean.getVoList();
UIXTable table = testingBean.getTable();
TableRowVO vo = list.get(table.getRowIndex());
vo.setReadOnlyFlag(true);
vo.setAccountType(vce.getNewValue().toString());
vo.setOtherType("");
if (vce.getNewValue().equals("3")) {
System.out.println("Setting false");
vo.setReadOnlyFlag(false);
}
list.set(table.getRowIndex(), vo);
table.setValue(list);
testingBean.setVoList(list);
FacesContext.getCurrentInstance().getExternalContext()
.getSessionMap().put("testingBean", testingBean);
} catch (Exception e) {
e.printStackTrace();
}
}
Is this behaviour expected? Or is there a workaround?
Interestingly, the "View Page Source" option in Firefox does not contain the text, even though I can see it on the page. I had to use FireBug to analyze the element which revealed the following:
<div class="af_inputText_content"
id="j_id_jsp_545172797_17:0:j_id_jsp_545172797_27">
tttt
</div>
Version used:
Trinidad 2.x
JSF 2.x
Tomcat 7.0
Ok, so I got it to work a while back but forgot to post the answer....
I used FacesContext to find the CoreComponent for the input text and then reset the components value.
Basically:
Find the CoreTable object
Find the CoreColumn object
Find the CoreInputText object
Reset the value for CoreInputText
The Modified JSP Code is as follows:
<tr:table emptyText="No Data" var="vo" autoSubmit="true" partialTriggers="accountType" id="voTable" value="#{testingBean.voList}" binding="#{testingBean.table}" width="50%">
<tr:column id="slNoCol">
<f:facet name="header">
<tr:outputText id="slNoHdr" value="Sl No" />
</f:facet>
<tr:outputText id="slNo" value="#{vo.slNo}" />
</tr:column>
<tr:column id="accountTypeCol">
<f:facet name="header">
<tr:outputText id="accountTypeHdr" value="Account Type" />
</f:facet>
<tr:selectOneChoice unselectedLabel="Select" id="accountType" value="#{vo.accountType}" autoSubmit="true" immediate="true" valuePassThru="true" valueChangeListener="#{testingAction.optionsChanged}">
<f:selectItems value="#{testingBean.options}" />
</tr:selectOneChoice>
</tr:column>
<tr:column id="otherTypeCol">
<f:facet name="header">
<tr:outputText id="otherTypeHdr" value="Other" />
</f:facet>
<tr:inputText value="#{vo.otherType}" columns="15" partialTriggers="accountType" id="otherType" readOnly="#{vo.readOnlyFlag}" immediate="true">
</tr:inputText>
</tr:column>
</tr:table>
The code for the modified valueChangeListener is as follows:
public void optionsChanged(ValueChangeEvent vce) {
try {
testingBean = (TestingBean) FacesContext.getCurrentInstance()
.getExternalContext().getSessionMap().get("testingBean");
ArrayList<TableRowVO> list = testingBean.getVoList();
CoreTable table = (CoreTable) FacesContext.getCurrentInstance()
.getViewRoot().findComponent("voTable");
CoreColumn column = (CoreColumn) table
.findComponent("otherTypeCol");
CoreInputText text = (CoreInputText) column
.findComponent("otherType");
text.setValue("");//This is the trick....
TableRowVO vo = list.get(table.getRowIndex());
vo.setReadOnlyFlag(true);
vo.setAccountType(vce.getNewValue().toString());
vo.setOtherType("");
if (vce.getNewValue().equals("3")) {
vo.setReadOnlyFlag(false);
}
list.set(table.getRowIndex(), vo);
table.setValue(list);
testingBean.setVoList(list);
FacesContext.getCurrentInstance().getExternalContext()
.getSessionMap().put("testingBean", testingBean);
} catch (Exception e) {
e.printStackTrace();
}
}
