[jboss-dev-forums] [Design of JBoss jBPM] - JSF EL - Cant Pass parameters
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());
| }
