a4j:commandLink doesn't work properly inside a4j:repeat

[manakor]

I have <a4j:repeat> which is inside <a4j:outputPanel>. This outputPanel is rerendered sometimes when needed. Inside <a4j:repeat> I have <a4j:commandLink> and this link doesn't support oncomplete event. It doesn't reach it when I click. Just click event is applied.

In case, I am using JSF 2 and RF4. And when I put commandLink outside of repeat, it works as have to.

Why it might happen?

Hi Nikita,

Just debug and confirm your backing bean methods those used to populate iteration data and other are working fine . Any such issue may cause such issue. Anyway commandlink will supprt oncomplete.

If still issue persists, please post your code.

Rgds,

a4j:commandLink has @oncomplete event attribute - can you check if you are using RF 4.0.0.Final?

I have tried on following sample it works for me:

<a4j:repeat id="a4jRepeat"
            iterationStatusVar="status"
            value="#{a4jRepeatBean.dataList}"
            var="item">
    <li>
        <h:inputText value="#{item.text}" />
        <a4j:commandLink id="link" value="Link2" render="@form" execute="@form">
                  <f:setPropertyActionListener target="#{a4jRepeatBean.selectedDataItem}" value="#{item}" />
        </a4j:commandLink>
          
        <h:outputText id="statusIndex" value="index=#{status.index}, "/>
    </li>
</a4j:repeat>

This is what I have:

<h:form>

     <a4j:outputPanel id="myPanel">

          <a4j:repeat var="result" value="#{searchResults.documents}">

               <a4j:commandLink render="myPanel" oncomplete="alert('Works!');" value="Result title">

                    <f:setPropertyActionListener  target="#{layout.changeViews['modalpanel'].value} " value="page.xhtml" />

               </a4j:commandLink>

          </a4j:repeat>

     </a4j:outputPanel>

</h:form>

And this code doesn't reach my alert at all!

Nikita,

What is the scope of 'searchResults' bean?

[manakor]

Nick, the scope of 'searchResults' bean:

<managed-bean-scope>request</managed-bean-scope>

[nbelaevski]

Try changing it to 'session'.

[manakor]

After I changed a scope to 'session' <a4j:commandLink> works fine with all it's event attributes. But than I need to empty (eq 0) the 'searchResults' bean every time I am performing an action to update it. Because it's not just updated once for a whole session. It's updated everytime I generate a new portion of results!

As I heard, there's another scope 'conversation', if I am not wrong. Maybe it's better to use this instead of creating an action to empty (eq 0) the 'searchResults' bean every time?

[nbelaevski]

Yup, you can use 'conversation'

[manakor]

Tryied to use 'conversation' scope for 'searchResults' bean, however it seems there are no such a type of scope. Found that just 2 new types came up with a lastest version of JSF 2: view and custom.

However, seems conversation scope doesn't exist at all. Nick, do you know, don't you?

[lfryc]

Conversation scope is included in CDI specification which is part of Java EE 6 spec.

You will need to use Java EE 6 compatible container (either JBoss AS 6 or Glassfish v3) or configure one of CDI implementations (Weld, CODI) to run in your container.
