a4j:support with valueChangeListener question

cash1981 Jun 9, 2008 9:56 AM

Hello.

I am wondering if anyone knows why the onchange event fires when you hit a commandbutton inside a form. The action of the command button should execute, not the valueChangeListener as it does in my example.

The find method is not executed if I change the value of selectOneMenu and push commandButton.

<h:form>
[snip]....[/snip]

<s:decorate template="/layout/display.xhtml">
 <ui:define name="label">Fylke</ui:define>
 <h:selectOneMenu valueChangeListener="#{searchProeveManager.updateKommune}" immediate="true">
 <s:selectItems value="#{fylkeList.resultList}" var="fylke" label="#{fylke.navn}" noSelectionLabel="Velg fylke"/>
 <a4j:support event="onchange" reRender="kommuneResultat"/>
 <s:convertEntity/>
 </h:selectOneMenu>
</s:decorate>
<s:div id="kommuneResultat">
 <s:decorate template="/layout/display.xhtml" rendered="#{searchProeveManager.kommuner.size > 0}">
 <ui:define name="label">Kommune</ui:define>
 <h:selectOneMenu value="#{searchProeveManager.kommune}" border="0">
 <s:selectItems value="#{searchProeveManager.kommuner}" var="kom" label="#{kom.navn}"/>
 </h:selectOneMenu>
 </s:decorate>
</s:div>

<h:commandButton id="findProeverSoek" value="Search" action="#{searchProeveManager.find}" reRender="searchResults" />

put phaseTracker to your web-inf libs and provide its log for request which was processed wrong.

Ok I did.

I don't understand much. But my find method is never executed which it should.

3. Re: a4j:support with valueChangeListener question

cash1981 Jun 10, 2008 5:15 AM (in response to cash1981)

I still have this problem. But here is a update. If I do not change the selectOneMenu then I can hit the command button and it calls the correct method.

But if I change the value of the selectOneMenu and then hit the commandbutton it will call the valueChangeListener method on the selectOneMenu instead.

Very strange behaviour.

Here is the complete xhtml:

So.. as I (and you for sure :) ) could see from the phaseTraker log - after 3rd phase next phase executed is sixth... That tell us about model wasn't successfully updated. So 5th phase not executed - so no valueChange listener.

If your searchProeveManager request scoped - you should change it to session use keepAlive fro this bean. And there is nothing about ajax. Just JSF question.

Ok I agree there seems to be something wrong. But thats why I need help :-)
If I understand you correctly you say that my searchProeveManager is request scoped, but I have session. The only thing is that the #fylkeList.resultList is not session scope.
I also tried to put searchProeveManager in <a4j:keepAlive> but that resultet in exception.

Here is my searchProeveManager. Maybe you can spot the problem, because I am blinded by my own code.
