David,

  So, an initial question here, getting started with the whole JSF (have to get book next week)
I got a basic loop going here:

  |       <c:forEach var="processDefinition" items="#{participantBean.allProcessDefinitions}">
  |       <tr  class="normal" onmouseover="this.className='hovered';" onmouseout="this.className='normal';" onclick="document.all['newExe#{processDefinition.id}\'].click()">
  |         <td class="selectable"><h:outputText value="#{processDefinition.name}" /> (<h:outputText value="#{processDefinition.id}" />) </td>
  |         <td class="selectable"><h:outputText value="#{processDefinition.version}" /></td>
  |         <td class="selectable"><h:outputText value="#{participantBean.allProcessInstances(***PID HERE***)}" /> </td>
  |         <td class="selectable">
  |           <h:commandLink action="#{participantBean.startNewProcessInstance}" id="newExe#{processDefinition.id}">
  |             <f:param name="processDefinitionId" value="#{processDefinition.id}"/>
  |             Start It!
  |           </h:commandLink>
  |         </td>
  |       </tr>
  |       </c:forEach>
  | 

This all works fine, shows all processdefinitions, and version and ID's fine.
So then in the loop, I would like to call out and get all the processInstances for each of these... And that doesnt seem to be working in any way I can do it.
I dont see how to pass a variable back into the function.

The function call itself should be fine:

  | 
  |   // hmm count all active processes instead?
  |   // first get count of all processes here, then try it in the webpage, then return list if needed
  |   //public int getAllProcessInstances(long processDefinitionId)
  |   public String getAllProcessInstances()
  |   {
  |     //return "12";
  |     System.out.println("PID:"+processDefinitionId);
  |     return  Integer.toString(jbpmBean.getJbpmContext().getGraphSession().findProcessInstances(processDefinitionId).size());
  |   }
  | 

Thanks, 
  James
