problem with h:selectBooleanCheckbox and a4j:support

[powerhouse_b]

Hello.

The fallowing code does not refresh the value of the boolean value "trusted" in my backing bean. I have put an System.out.println in the setter to know when it is being called. but this never happens. Only the getter is called and it returns corectly. This is the code:

<h:selectBooleanCheckbox id="chkTrusted" value="#{loginBean.trusted}" >
 <a4j:support event="onchange" />
</h:selectBooleanCheckbox>

I have also tried (i included all superior tags)

<f:view>
//....
<rich:panel style="width:435px ">
//...
 <h:form>
//...
 <h:panelGrid>
 <a4j:outputPanel id="checkboxPanel" >
 <h:selectBooleanCheckbox id="chkTrusted" value="#{loginBean.trusted}" >
 <a4j:support event="onchange" reRender="checkboxPanel"/>
 </h:selectBooleanCheckbox>
 </a4j:outputPanel>
//...

1) outputPanel is not a component that change processing.

2) If the setter isn't called - place rich:messages somewhere or use phasetracker to check where the processing breaks from server logs.

This is my output with phasatracker. I wrote an System.out.println in every getter and setter, so when you see something begining with "setting" or "getting", it is from me. I see the null parameter ERROR, but i don't know where it might come from.

Pls ignore the previous output, i forgot to put an System.out.println in the getter for the login button (it is binded to a UICommand).
