ui:repeat with action does not work

[nimo22]

Why does this work?:

Version 1:

<h:panelGroup>

        <h:form prependId="false">

                    <ul>

                        <a4j:repeat var="_t" value="#{bean.list}">

                            <li><a4j:commandLink action="#{bean.action(_t)}" render=":c1" value="#{_t}" execute="@this"/></li>

                        </a4j:repeat>

                    </ul>

                </ui:repeat>

        </h:form>

</h:panelGroup>

and ths not:

Version 2:

<h:panelGroup>

        <h:form prependId="false">

                    <ul>

                        <ui:repeat var="_t" value="#{bean.list}">

                            <li><a4j:commandLink action="#{bean.action(_t)}" render=":c1" value="#{_t}" execute="@this"/></li>

                        </ui:repeat>

                    </ul>

                </ui:repeat>

        </h:form>

</h:panelGroup>

When clicking commandLink in version 2, then no action is fired.

When clicking commandLink in version 1, then action is fired as expected.

Why does version 2 not work?

Facelets' ui:repeat has indeed bugs in certain situations. As to the difference with the other two, it boils down that it's not an UIData component while the other two are.

Ajax4jsf UIRepeat extends UIData.
Tomahawk's HtmlDataList extends UIData.
Facelets' UIRepeat does not extend UIData.

The inheritable codebase provided by UIData is pretty mature (although it is not always as efficient as it ought to be). The Facelets' UIRepeat still needs to be polished more. The ui:repeat can't extend UIData, because it's part of Facelets, the view technology, not of JSF, the component based MVC framework. It was also initially developed by a different team.

Since it's unclear what issue exactly you're talking about, it's hard to tell whether it's actually one of its known bugs or just a misinterpretation/abuse. At least, here is an overview of all known bugs related to ui:repeat.

What is the scope of your bean, @RequestScoped?

[nimo22]

Bean is @SessionScoped.

I guess, the error lies in that what siva have said. thanks.
