problem with a4j:actionparam

[orkun]

hello

when I click on an image I want to pass a value (88) to a variable(imagePainter.xx).

I tried this:

<a4j:mediaOutput id="telephone" element="img" mimeType="image/jpeg"
createContent="#{imagePainter.drawImage}" coords="10,10,60,60">
<a4j:support event="onClick" reRender="xcoord">
<a4j:actionparam name="param1" value="88" assignTo="#{imagePainter.xx}" />
</a4j:support>
</a4j:mediaOutput>
<h:outputText id="xcoord" value="#{imagePainter.xx}"></h:outputText>


but it does not work

I am wondering what the wrong is ?

regards

This test worked for me:

<h:form>
 <a4j:jsFunction name="setXCoord" reRender="xcoord">
 <a4j:actionparam name="param1" value="88"
 assignTo="#{mediaBean.xx}" />
 </a4j:jsFunction>
 </h:form>

 <h:form id="mediaBeanForm">

 <a4j:mediaOutput element="img" cacheable="false"
 createContent="#{mediaBean.paint}" value="myimage.png"
 mimeType="image/jpeg" onclick="setXCoord();">
 </a4j:mediaOutput>
 <h:outputText id="xcoord" value="#{mediaBean.xx}"/>



 </h:form>
