Open modalPanel with a parameter

I'd like to have modal panel in a page, but I would like to be able to supply a parameter开发者_运维问答. Now I do it like this:

Panel:

<rich:modalPanel id="panel" width="500" height="435">
  ...
  [#{bean.tempId}]
</rich:modalPanel>

button to open panel:

<ui:repeat ... var="item">
  <h:form>
    <a4j:commandLink id="link" oncomplete="Richfaces.showModalPanel('panel');" reRender="panel">
      <f:setPropertyActionListener value="#{item.id}" target="#{bean.tempId}"></f:setPropertyActionListener>
      text...
    </a4j:commandLink>
  </h:form>
</ui:repeat>

This doesn't seem to be the best approach. What would be a better one?

In case you don't want it to go to the server, it is not so much JSF related. in oncomplete you can assign the value to a javascript variable and use that variable in the panel.
