ReRenderd UIcommand not working

[jmatters]

Hello,

I am currently encountering a problem when I try to call any UIcommand element be it <h:command... or <rich:command... that was generated via a reRender of a h:dataTable. The defined action is simply not called.

If the element is present in the list from the page rendering on, the UIcommand works. If the element are added through a reRender the problem appears.

I'm using richfaces 3.1.3.GA with seam 2.0.0.GA on jboss 4.2.2.GA.

I think I have read about this problem before, but is there any workaround, or is there a jira issue for that?

you may not reRender that component that didn't present in DOM tree before request. Instead you should reRender some parent that was actually on the page before request.

Hi, thanks for your reply!

I am rerendering a parent object that is present from the page rendering on. It's a datatable:

<h:form>
 <h:dataTable id="personSearchResult" var="person"
 value="#{personList.searchPersons}">
 <h:column>
 <a4j:commandLink action="#{CaseHome.addPerson(person.id)}" value="#{person.givenName} #{person.familyName}" reRender="personList" ></a4j:commandLink>
 </h:column>
 </h:dataTable>
</h:form>

Now #{personList.searchPersons} is null at page rendering. But then I've got:

<h:form>
 <h:inputText value="#{personList.person.givenName}">
 <a4j:support event="onkeyup" requestDelay="400" reRender="personSearchResult" action="#{personList.resultList}"></a4j:support>
 </h:inputText>
</h:form>

and when #{personList.person.givenName} is not empty #{personList.searchPersons} returns a list. The table and the a4j:commandLinks are rendered perfectly fine, but the command links don't call the action...

Any hints appreciated!

you need to define the ide of the command component explicitly if it is in the rerendered area. Otherwise, the id of the regenerated component might not match the id assigned during the component tree restoring of the first JSF phase. This mismatch is not only one, but a very strong reason when the action is not processed on postback.

Hi, I added an id to the commandLink:

<a4j:commandLink id="addPersonLink" action="#{CaseHome.addPersonX(person.id)}" value="#{person.givenName} #{person.familyName}" reRender="personList" ></a4j:commandLink>

Sadly the action is still not being called...

The rendered commandLink now looks like this:

<a href="#" id="personSearchList:0:j_id86:addPersonLink" name="personSearchList:0:j_id86:addPersonLink" onclick="A4J.AJAX.Submit('_viewRoot','personSearchList:0:j_id86',event,{'parameters':{'personSearchList:0:j_id86:addPersonLink':'personSearchList:0:j_id86:addPersonLink'} ,'actionUrl':'/case.seam?javax.portlet.faces.DirectLink=true'} );return false;">Test Person</a>

what the scope of the bean you use for the list ?

[jmatters]

The bean is a seam component. It's kept in the seam coversation context.

I solved the problem by moving the list to a stateful bean, it's scope is also the seam conversation context.

Thanks for your help!
