Create actionparam dynamically

[leiras]

Hi,

i have to convert the code above to java.

<a4j:support event="onclick" reRender="imgGrafico" oncomplete="javascript:Richfaces.showModalPanel('mpGrafico')" actionListener="#{auditoria.gerarGraficoAuditoria}">
 <a4j:actionparam name="xxx" value="#{item.id}" assignTo="#{auditoria.idAuditoriaSelecionada}" />
</a4j:support>

I have no problem with the a4j:support. But i don't know how to pass the a4j:actionparam to java. I tried the following code, but it did not work:

HtmlActionParameter actionparam = new HtmlActionParameter();
actionparam.setName("xxx");
actionparam.setValueBinding("vb", application.createValueBinding("#{item.id}"));
actionparam.setAssignToBinding(application.createValueBinding("#{auditoria.idAuditoriaSelecionada}"));
supportClick.addActionListener(actionparam);

Any suggestion? Thanks a lot!

I made a little change, but it still don't work.

actionparam.setParent(supportClick);

What am I doing doing wrong?
