-----------------------------------------

Hi

I have done this test:

			<h:selectOneMenu id="si" binding="#{selectItemBean.component}"
				value="#{selectItemBean.value}"
				valueChangeListener="#{selectItemBean.processValueChange}"
				onchange="submit()">
				<f:selectItem itemLabel="Choose One" itemValue="choose_one" />
				<f:selectItems value="#{selectItemBean.list}" />
			</h:selectOneMenu>

                        <!-- THIS TAG HERE LET ME SEE WHAT VALUE HAS ON RENDER RESPONSE -->
                        <h:outputText value="#{selectItemBean.value}"></h:outputText>

The bean is on request scope. I have tested the following environments:

jsf ri 1.2_05
myfaces 1.2.1-SNAPSHOT
myfaces 1.2.1-SNAPSHOT + faceletes

All has the same behavior. All call the setter, but after valueChange method is called, before it, value property of the bean is allways null.

I don't believe that tomahawk affects in something.

Could you send more details to try to reproduce this issue, please?

> I don't know whether this error only occurs in combination with facelets, but this is what happens: the "return value: of a h:selectOneMenu in always "null" in the sense that the SETTER IS NEVER CALLED (-> value stays null)
> So for:
> <h:selectOneMenu value="#{testOverviewBean.compoundCodeFromMenu}" valueChangeListener="#{testOverviewBean.fillTestSeqNrs}" onchange="submit();">
> 		<f:selectItem itemLabel="Choose One" itemValue="choose_one"/>
> 		<f:selectItems value="#{utilBean.compoundCodes}" />
> </h:selectOneMenu>
> ... the setCompoundCodeFromMenu() is never called, which always leads to NPEs later on.
> As this is one of the few core components ("h:"), I think labelling it "blocking" is justiefied.
