javax.el.MethodNotFoundException althoug method is present

[wurzelbutz]

Hi

I created a litte application where i can assign jbpm tasks to differnt users.
I have a page which shows all tasks assigned to a user. on this page there is a "start" button which starts the tasks and displays an other page which shows task details.
On the details page there are a "end" and a "pause" button which should end (works well) or suspend (doesnt work) the task.

The problem is that after starting a task and later on pressing the "pause" button an exception is thrown.

17:55:57,640 FATAL [application] javax.el.MethodNotFoundException: /task.xhtml @36,61 action="#{processSystem.pause}": Method not found: ProcessSystemAction:52q2q6-kms9k1-fnq7rv1k-1-fnq7uhur-c.pause()
javax.faces.el.MethodNotFoundException: javax.el.MethodNotFoundException: /task.xhtml @36,61 action="#{processSystem.pause}": Method not found: ProcessSystemAction:52q2q6-kms9k1-fnq7rv1k-1-fnq7uhur-c.pause()
        at javax.faces.component.MethodBindingMethodExpressionAdapter.invoke(MethodBindingMethodExpressionAdapter.java:81)
       ...


The interesting part of the deails page:
`
<div class="rvgFind">
<fieldset class="rvgFieldSet">
<legend>Task</legend>
<div class="rvgInputs">
<div>
             Title:
<h:inputText value="#{taskInstance.name}"/>
</div>
<div>
             Description:
<h:inputTextarea value="#{taskInstance.description}" rows="8"/>
</div>
</div>
<div class="rvgActions">
<h:commandLink action="#{processSystem.done}">
<h:commandButton value="End"/>
<f:param name="taskId" value="#{taskInstance.id}"/>
</h:commandLink>
<h:commandLink action="#{processSystem.pause}">
<h:commandButton value="Pause"/>
<f:param name="taskId" value="#{taskInstance.id}"/>
</h:commandLink>
</div>
<span class="rvgActions">
<h:commandLink action="home" value="Go back home"/>
</span>
</fieldset>
</div>
`

and the processSystem bean:
`
@Stateful
@Name("processSystem")
@Scope(ScopeType.BUSINESS_PROCESS)
public class ProcessSystemAction implements ProcessSystem {
        @In FacesMessages facesMessages;
        @CreateProcess(definition="WartungKAV")
  public String newProcess() {
      System.out.println("new instance");
          return "home";
  }

  @StartTask(taskIdParameter="taskId")
  public String start(){
          System.out.println("Start");
          TaskInstance.instance().setStart(Calendar.getInstance().getTime());
        //  facesMessages.add("ticketAdded","Task started");
        return "task"; 
  }
  @BeginTask
  public String resume(){
         
          return "task";
  }

  public String pause(){
          System.out.println("Suspending...");
          TaskInstance.instance().suspend();
          System.out.println("Suspended");
          return "assignedProcesses";
  }
  @EndTask
  public String done(){
          System.out.println("done: "+TaskInstance.instance().getId());
          return "home";
  }

  public String showme(){
          System.out.println("Showing: "+TaskInstance.instance().getId());
          return "task";
  }
  @Destroy @Remove
  public void remove(){
         
  }
`
What am i doing wrong?

sorry for not using the code tags i just couldn't get them to work...

[wurzelbutz]

i could solve the problem by adding the method(s) to the interface ProcessSystem

Yep, except for the Remove method, anything you want visible in the page context must be the Interface.  I do recall reading that the next version of EJBs will remove this requirement, but I do not have confirmation.
