Richfaces <a4j:ajax> and <rich:popupPanel> "conflict" - ajax

I've stumbled upon a strage behavior of richfaces. Some background about my view structure:
It's mainly a <rich:extendedDataTable> where a click on a row displays info about it on a <a4j:outputPanel>
Also, each row has a context menu with items like "Create", "Edit", etc... that pops a <rich:popupPanel>
The component structure is this:
<h:panelGrid columns="2">
<h:column>
<rich:dataScroller for="testTable" maxPages="7"/>
<rich:extendedDataTable id="testTable" value="#{testController.items}" rendered="#{testController.items.rowCount != 0}"
selection="#{testController.selectedRow}" noDataLabel="No results to show" var="test" rows="20"
style="width: 790px" selectionMode="single">
<a4j:ajax execute="#form"
event="selectionchange"
listener="#{testController.selectionListener}"
render=":res"/>
{columns to display}
</rich:extendedDataTable>
</h:column>
<a4j:outputPanel id="res">
<rich:panel header="Selected Rows:" rendered="#{not empty testController.selectedRows}">
<rich:list type="unordered" value="#{testController.selectedRows}" var="t">
<h:outputText value="#{t.name}"/>
<br/>
<h:outputText value="#{t.details}" converter="#{testConverter}"/>
</rich:list>
</rich:panel>
</a4j:outputPanel>
</h:panelGrid>
<rich:contextMenu target="testTable" mode="ajax" id="contextMenu">
<rich:menuItem label="Edit" render="popupEdit" oncomplete="#{rich:component('popupEdit')}.show();" mode="ajax"/>
</rich:contextMenu>
<rich:popupPanel id="popupEdit" modal="true" autosized="true" resizeable="false" moveable="false" domElementAttachment="form">
<rich:hotKey key="esc" onkeyup="#{rich:component('popupEdit')}.hide(); return false;"/>
<f:facet name="header">
<h:outputText value="Edit Test"/>
</f:facet>
<f:facet name="controls">
<h:outputLink value="#" onclick="#{rich:component('popupEditar')}.hide(); return false;">
<h:graphicImage value="/resources/css/images/fechar_janela.png" width="20" height="20"/>
</h:outputLink>
</f:facet>
<h:panelGrid id="popupEditContent" columns="2">
... {display of info}
<a4j:commandButton value="Salvar" actionListener="#{testeController.update()}" render="tabelaTestes, contextMenu"/>
<h:panelGroup id="messagePanel" layout="block">
<rich:messages ajaxRendered="true" />
</h:panelGroup>
</h:panelGrid>
</rich:popupPanel>
And now the strange behaviour (using NetBeans):
Deploy the app from NetBeans;
Open the URL of the deployed project on browser (Firefox) . The <a4j:ajax> inlined in the table doesn't work, I know this because the 'testController.selectionListener' is not called and the details are not displayed (it sets the attribute current in the backing bean). The contextMenu works but the popupPanel shows null or empty properties in all fields (the current attribute is not set);
Go back to the IDE, remove all the <rich:popupPanel> section and save the file;
Back in the browser, hit F5 and click a row. Now the <a4j:ajax> works and calls testController.selectionListener, showing the details in <a4j:outputPanel>. The context menu works but (obviously) the panel does not pop;
In the IDE, put back the <rich:popupPanel> section and save the file;
Now refresh the page again, and everything works, details are shown and the Edit pop up shows the right info of the selected row.
I have tried deploying it without the <rich:popupPanel> section and the selecionListener gets called. I think that the problem is deploying the page with both <a4j:ajax> and <rich:popupPanel> sections, hence the "conflict".
I took the structure from the richfaces showcase and made changes. I noticed that in the showcase, the <rich:popupPanel> is placed outside the <h:form> tag, wich in my project is placed in the template.xhtml (so a topmenu page works). Is it possible that the error is caused by this placement?
Could this be considered a bug to file in the richfaces project or am I missing something there?
Is there a workaround or solution?
Thank you very much!

I think I have solved it. I set the id attribute to "form" in the <h:form> tag, in template.xhtml, so now it looks like this:
<h:body>
<h:form id="form">
<div id="top" class="top">
<ui:insert name="top">Top</ui:insert>
</div>
<div id="content" class="center_content">
<ui:insert name="content">Content</ui:insert>
</div>
</h:form>
</h:body>
It was the only change I made and now all the components work at first post-deploy.
Edit: Found the solution when searching for another problem: JSF action call on secon click

Strange behavior with f:ajax: Toggle between views does not update rendered code in browser if <ui:repeat> has an <h:outputText> with escape="false"

I want to switch between two views and report two lists outputs on each view.
Toggle between views uses a <h:commandLink> with an <f:ajax> element.
Each view generates the output of the lists with <ui:repeat>
The output works fine, if the <h:outputText> within the <ui:repeat> does not specify the escape attribute.
After adding escape="true" to the <h:outputText> the following happens:
After clicking the <commandLink> the <commandLink> the browser does not update the rendered output.
After clicking the myController.toggleView changes listData.showFirst (boolean)
After clicking the <commandLink> the source code of the website changes to what should be there.
Summary: Clicking the <commandLink> updates the outputed source code, but the browser does not update the output, when the <h:outputText> in the <ui:repeat> uses the attribute escape="true".
Here the code:
<h:form prependId="false">
<h:commandLink actionListener="#{ myController.toggleView }" value="Click">
<f:ajax render="#form" />
</h:commandLink>
<h:panelGroup rendered="#{ listData.showFirst }" id="firstView">
<ui:repeat var="house" value="#{ listData.houses }">
<h:outputText value="#{ house.description }" escape="false" />
</ui:repeat>
</h:panelGroup>
<h:panelGroup rendered="#{ !listData.showFirst }" id="secondView">
<ui:repeat var="street" value="#{ listData.streets }">
<h:outputText value="#{ street.description }" escape="false" />
</ui:repeat>
</h:panelGroup>
</h:form>
Any ideas?

update content page from menubar primefaces 3 and jsf 2 ajax

well first ill explain what im tryng to do, i have a index.xhtml page where i include menu.xhtml with a menubar of primefaces, in menu.xhtml in have a panel id=contenido where i want to update depending of the menuitem clicked, i already get update that panel but the problem is when i update to another page for example in default is home.xhtml and i update to enviarsol.xhtml then the command button from enviarsol.xhtml is not working, im new at this and i already tried some different ways of updating the panel, im thinking that the problem is that the bean of enviarsol.xhtml is not managed or something like that,also im doing this way because i want to refresh only that panel and not all the page, someone help me please.
index.xhtml:
<h:form>
<img src="resources/homeheader.jpg" width="300" height="113" alt="homeheader"/>
<div style="background-color: white">
<img src="resources/Logos.jpg" width="1024" height="166" alt="homeheader"/>
</div>
<p:panel id="centerpage" >
<ui:include src="WEB-INF/menu.xhtml"/>
</p:panel>
</h:form>`
menu.xhtml:
<p:menuitem value="Contactos" icon="ui-icon-arrowreturnthick-1-w" actionListener="#{bnmenu.btnEditarContacto(e)}" update="contenido"/>
<p:panel id="contenido" >
<ui:include src="#{bnmenu.url}"/>
</p:panel>
bnmenu.java:
private String url;
public bnmenu() {
url="home.xhtml";
}
public void btnEditarContacto(ActionEvent e)
{
url="enviarsol.xhtml";
}
home.xhtml:
<p:panelGrid columns="2" style="border-width: 0px">
<p:commandButton value="Consultar" actionListener="#{bnhome.btnlogin(e)}" update="txt1"/>
<p:inputText id="txt1" value="#{bnhome.txtUsuario}"/>
</p:panelGrid>
enviarsol.xhtml:
<p:panelGrid columns="2" style="border-width: 0px">
<p:outputLabel for="txtcorreo" value="Correo: "/>
<p:inputText id="txtcorreo" value="#{bnSolicitud.correo}"/>
<p:outputLabel for="txtmensaje" value="Mensaje: "/>
<p:inputText id="txtmensaje" value="#{bnSolicitud.mensaje}"/>
<p:commandButton value="Enviar" actionListener="#{bnSolicitud.btnSolicitar(e)}" update="messages"/>
</p:panelGrid>`
i included this:
<context-param>
<param-name>javax.faces.PARTIAL_STATE_SAVING</param-name>
<param-value>false</param-value>
</context-param>
and now it is working but i dont know what more effects will this cause
well now it works but only once when i click in commandbutton from enviarsol.xhtml
Finally it appears working fine, i changed #RequestScoped by #SessionScoped in bnmenu
Are you sure that you really want ajax navigation? It is very frustrating for a user not being able to use the browsers urlfield or navigation buttons, and it will be harder for you to code aswell. Consider transforming index.xhtml into a template file as described at http://www.mkyong.com/jsf2/jsf-2-templating-with-facelets-example and using normal navigation.

Ajax not working with primefaces

In my JSF page I have form when I click submit button in the same page I need to show an static content. But When I click <p:commandbutton> nothing appears in the page. When I put ajax="false" then only action taken place but the Static content display in new page.
In my Backing bean I have used Session scoped. I am using JSF 2.0 and Primefaces 3.2.
My JSF Page.
<h:form>
<h:panelGroup rendered="#{not license.showForm}">
<p:panel header="License Key Request" >
<h:panelGrid columns="2" >
..
<h:outputText value="Bla bla"/>
..
<h:outputText value="Bla Bla" />
</h:panelGrid>
<TABLE>
..
<h:outputLabel for="name" value="Requestor Name : *" />
..
<p:inputText id="name" value="#{license.name}" required="true" requiredMessage="Name is required."/>
..
<h:outputLabel for="company" value="Company : * " />
..
<p:inputText id="company" value="#{license.company}" required="true" requiredMessage="Company is required."/>
..
</table>
<p:commandButton value="Form" id="btnAdd" process="#form"
action="#{license.add}" />
..
</table>
</p:panel>
</h:panelGroup>
<h:panelGroup rendered="#{license.showForm}" >
<h:outputText value="Bla Bla"/>
</h:panelGroup>
</h:form>
Your source code is somewhat confusing (e.g. you have two closing table tags). But I assume that you want to show the panelGroup at the bottom if the button is clicked.
The easiest way would be to add an update ="#form" to your commandButton:
<p:commandButton value="Form" id="btnAdd"
process="#form" update="#form"
action="#{license.add}" />
You don't need to update the whole form but only the specific component. Then you need to give the panelGroup an id attribute and use this attribute instead of #form. However, since it is not clear for me how your naming containers are organized, it could be puzzling to find the correct relative id.

How to skip validation on certain fields in JSF 2 when required

I have two p:dialog. Each one contains some input fields which are marked as required. Only one dialog is shown at a time but when I submit on any of the dialog, JSF also validates the input fields of the dialog which is not shown. What is the best approach to skip the validations in JSF 2 for the dialog which is not shown. One approach could be that I set the required="condation". But dont know what that condition could be and is it goin to work.
Each dialog is initially hidden. Each one has its own button to show. When one is active and I click the save button there is a validation error even when the required field has values. The validation error comes from the inactive dialog panel. May be it give some idea what i am trying to do.
UPDATE
<p:dialog header="Edit Group" widgetVar="dialog_groupEdit" resizable="false"
width="300" showEffect="bounce" hideEffect="explode" modal="true" position="center">
<h:panelGrid id="panel_groupEdit" columns="2">
<h:outputText value="Group Name: "/>
<h:inputText id="input_gnameEdit" size="26" value="#{groupBean.selectionGroup.gname}" required="true" requiredMessage="Edit Group: Name is required."/>
<h:outputText value="Description:"/>
<h:inputTextarea rows="6" cols="23" value="#{groupBean.selectionGroup.description}"/>
<div></div>
<p:commandButton value="Save" action="#{groupBean.saveGroupChanges}" oncomplete="#{args.validationFailed ? '':'dialog_groupEdit.hide()'}"
update="panel_groups panel_groupEdit" style="float:right;"/>
<div></div>
<p:message for="input_gnameEdit"/>
</h:panelGrid>
</p:dialog>
<p:dialog header="New Group" widgetVar="dialog_groupCreate" resizable="false"
width="300" showEffect="bounce" hideEffect="explode" modal="true" position="center">
<h:panelGrid id="panel_groupCreate" columns="2">
<h:outputText value="Group Name: "/>
<h:inputText id="input_gnameCreate" size="26" value="#{groupBean.createGroup.gname}" required="true" requiredMessage="New Group: Name is reqired."/>
<h:outputText value="Description:"/>
<h:inputTextarea rows="6" cols="23" value="#{groupBean.createGroup.description}"/>
<div></div>
<p:commandButton value="Save" actionListener="#{groupBean.saveGroupCreate}" oncomplete="#{empty groupBean.createGroup.gname ? ' ':'dialog_groupCreate.hide()'}"
update="panel_groupCreate panel_groups" style="float:right;"/>
<div></div>
<p:message for="input_gnameCreate"/>
</h:panelGrid>
</p:dialog>
One approach could be that I set the required="condation".
This is going to be clumsy. Just put each individual form in its own separate <h:form> component, or use the process attribute of the <p:commandButton> to identify the region you'd like to process.
<p:commandButton process="panel_groupEdit" ... />
...
<p:commandButton process="panel_groupCreate" ... />
Having a "God" form is in any way a poor practice.

Understanding PrimeFaces process/update and JSF f:ajax execute/render attributes
How to use <h:form> in JSF page? Single form? Multiple forms? Nested forms?
When you are using <p:dialog some of the good practices as advised on the PF forum are -
Never put your <p:dialog inside any other component. Place it somewhere so that it falls right under the <h:body.
Give every <p:dialog it's own form. But, don't place the dialog inside the form, place the form inside the dialog. It's not good to update the dialog itself, only it's content. (I think this should solve your issue also.)
e.g.
<p:dialog widgetVar="dlg" ...
<h:form ...
<h:panelGroup id="dlgContent" ...

hide component, then show it, values are not saved

I have a JSF 2.0 web app with ajaxified tabs.
To switch tabs I show one and hide the others (Either with a conditional render="#{x==y}" or with with display:none/block through conditional styleClass`ing.
In either case I get the tabs to show or hide correctly.
The problem is that the values entered in the input boxes are not retained throw a hide/show of a tab (In other words, if you enter some values in tab 1, go to tab 2 and back to tab 1, the values are not retained).
I use this <f:ajax> tag on tab selection (ignited by a hash change event)
<h:form id="processFragment" prependId="false" class="hide">
<h:inputText id="fragment" value="#{fbean.fragment}">
<f:ajax event="change" execute="contentSection" listener="#{fbean.processFragment}"
render="contentSection" />
</h:inputText>
</h:form>
<div>
<h:form id="contentSection">
<ui:insert name="content" />
</h:form>
</div>
Thanks!
The code the display the tab bar and the tab contents:
<ui:define name="content">
<f:view>
<h:panelGroup styleClass="navBar">
<ul>
<ui:repeat value="#{hello.tabList}" var="tab">
<li onclick="window.location='\##{tab.tabHash}'"><h:panelGroup
styleClass="#{hello.chose == tab.tabHash?'activeTab':''}">
<h:outputText value="#{tab.tabName}" />
</h:panelGroup>
</li>
</ui:repeat>
</ul>
</h:panelGroup>
<h:panelGroup id="contentPanels" styleClass="tabContentBar">
<c:forEach items="#{hello.tabList}" var="tab">
<h:panelGroup rendered="#{hello.chose == tab.tabHash}">
<!-- <h:panelGroup styleClass="#{hello.chose == tab.tabHash?'shownTabContents':'hiddenTabContents'}"> -->
<ui:include src="#{tab.tabFile}" />
</h:panelGroup>
</c:forEach>
</h:panelGroup>
</f:view>
</ui:define>
Finally, the contents of the specific tab:
<h:outputText value="TESTING 1" />
<h:panelGroup styleClass="formField">
<h:outputText value="Enter Value:" />
<h:inputText value="#{general.name}" />
</h:panelGroup>
UPDATE
Just noticed that even if I don't hide the tabs and press a button, the value is reset. Investigating...
The values will only be retained if you use a view scoped bean and the desired form is been submitted to the server side during (or right before) tab navigation.
As an alternative, you could render all tabs at once and use only JS/CSS to show/hide tab contents. CSS-hidden inputs will still be submitted to the server side.
