[jboss-dev-forums] [Design of JBoss jBPM] - JSF EL - Cant Pass parameters

[falazar]

I am having a problem passing parameters in the JSF file

I am looping through all process definitions, and trying to then call a function that can return the # of instances of that process.  But its not working. There doesnt appear to be any way to pass a parameter back into the bean from the jsf page.



  |       <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">
  | 
  | PROBLEM ON NEXT LINE
  | <h:outputText value="#{participantBean.allProcessInstances(processDefinition.id)}" /> </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>
  | 

  // 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:"+PID);
  | 
  |     return  Integer.toString(jbpmBean.getJbpmContext().getGraphSession().findProcessInstances(109).size());
  |     //return  Integer.toString(jbpmBean.getJbpmContext().getGraphSession().findProcessInstances(processDefinitionId).size());
  |   }
