a4j:commandLink not working in dynamically generated rich:tabPanel

[scott.jones618]

I am using Facelets, JSF 2.0, & RichFaces 4.0.0.

I am able to use a4j:commandLink with rich:tabPanel with a static rich:tab without a problem:

<h:form id="form">
  <rich:tabPanel switchType="client">
    <rich:tab name="tab" label="tab" title="tab">
      <a4j:commandLink action="#{someBean.someAction}" rendered="true" value="Works fine!"/>
  ...

However, when I try to create tabs dynamically (a requirement of my project) and have links on the tabs, the links stop working.  They appear and look like hyperlinks but nothing happens when I click on them.

<h:form id="form">
  <rich:tabPanel switchType="client">
    <c:forEach items="#{someBean.items}" var="eachItem">
      <rich:tab name="#{eachItem.name}" label="#{eachItem.name}" title="#{eachItem.description}">
        <a4j:commandLink action="#{someBean.someAction}" value="Doesn't work!"/>
...

Any ideas?

Hi Scott,

Does someBean have scope with lifetime longer than request?

[scott.jones618]

Yes, it's SessionScoped.

@ManagedBean
@SessionScoped
@Transactional
public class SomeBean {
    //blah, blah...

    public List<ItemDTO> getItems() {
        //queries database and returns non-empty list...
    }

    public String someAction() {
        return "fooBar.jsf"
    }
}

I read elsewhere that you should use a4j:htmlCommandLink but that's not available in RichFaces 4.0.0.

could you try just to check with h:command?

not it should not be the case. it was such workaround for h:commandLink..

I tried using h:commandLink and I got an IllegalArgumentException (see this thread: http://community.jboss.org/thread/167979).  It was that error that lead me to try a4j:commandLink as a work-around.

I'm seeing exactly the same thing. If you attempt to use any type of commandLink inside a list of some sort the action on that link is not called. I've also tried commandButton and the a4j variations of those.

<rich:list var="venue" value="#{searchManager.results}" type="definitions" stateVar="status">
     <h:form>
            <h:commandLink value="RATE IT" immediate="true" action="#{venueScore.selectVenue}" />
     </h:form>
</rich:list>

The position of the form also doesn't matter.

<h:form>
     <rich:list var="venue" value="#{searchManager.results}" type="definitions" stateVar="status">
            <h:commandLink value="RATE IT" immediate="true" action="#{venueScore.selectVenue}">
            </h:commandLink>
     </rich:list>
</h:form>

If I just have the link by itself (no list) it works.

Any help would be greatly appreciated.

Was able to fix this. The link is not found because the list of results is not available when the link is clicked. Changing the searchManager bean to have an @ViewScope fixed the problem.

Hello.  I took over work from Scott, the OP.   I am still having this error and cannot find a workaround.  The Bean is @SessionScoped the list generating the tabs is not changeing.  Has anyone else run in to this and been able to fix it.  I need to use a h:commandLink btw

Jeff, can you try using ui:repeat instead of c:forEach? I think it should slot in without having to

change too much code.

edit: sorry, silly suggestion!
