a4j:support + valueChangeListener doesn't work anymore

[gena777]

Hello i've got some troubles with the invocation on valueChangeListener on requests sent by h:commandButton ajaxified by a4j:support:

<tr:form useUpload="true">
<a:region>
 <a:outputPanel ajaxRendered="true" keepTransient="true">
 <tr:inputFile valueChangeListener="#{imageUploader.uploadFileChange}"
 simple="true"
 id="fileinput"/> <h:commandButton value="Upload" action="#{imageUploadController.uploadImage(imageUploader)}">
<a4j:support action="#{imageUploadController.uploadImage(imageUploader)}" disableDefault="true" reRender="messages_div" status="globalStatus" event="onclick" />
</h:commandButton>

 </a:outputPanel
</a:region>
</tr:form>

If i comment out the a4j:support block it works as it should: the valueChangeListener is called and the upload proceeds.

here is the phaseTracker output:

What am i doing wrong?

Thanks for any help, Gena

I did investigate deeper and find out that the AjaxViewRoot doesn't contain the expected valueChangeEvent in an events array (method broadcastEvents) if the a4j:support is used and it contains such an event if a4j:support is removed.

I also recognized, that if a4j:support has got any javascript error on submit, the only value change listener is fired but not the action method.
