    Macrosubstitutions

      Hello,

       

      I have a table ot persons, and I want to use rich:contextMenu with the rich:componentControl.

       

      Say that I pass the personId parameter like this:

       

       

      <rich:componentControl event="onclick" for="menu" operation="show" >
           <f:param value="#{person.personId}" name="personId"/>
      </rich:componentControl>
      

       

      Now, from a rich:contextMenu item I want to call an action that will fetch the person from the DB and reRender a rich:panel

       

      <rich:menuItem ajaxSingle="true" action="#{myBean.personMap[personId] = true}" reRender="anIdPrefix{personId}">
          <h:outputText value="Expand Person {personId}" />
      </rich:menuItem>
      

       

      The action of clicking the menuItem is to change a value in a map to true, and then reRender a component.

       

      Normally, I would use microsubstitutions fo "resolve" the personId variable inside the rich:menuitem. Normally this is resolved by putting it inside curly brackets, like this: {personId}.

       

      However, I want to execute an action, and that requires an EL expression, which somehow messes up things. Possibly because the EL expression requires its own brackets.

       

      Any idea how I should invoke the action with the personId as a parameter?

       

      Cheers!
