Problem Ending a Task

[mdarr]

Ok so i have followed along with the dvd-seam example.

However I am apparently doing something wrong here.

I start the task ... i can see it in the debug.seam page.

But when i go to end it. Nothing happens.

Task as defined in the xml ->

<task-node name="working" end-tasks="true">
 <task name="taskWorking" description="Tasks being worked on">
 <assignment pooled-actors="ticket-worker"/>
 </task>

 <transition name="next" to="finished"/>
 </task-node>

The code on the task list where you start the task ->

 <s:button action="#{ticketWorking.viewTask}" taskInstance="#{task}"
 value="Set Task to Working"/>

The Class ->

@Stateful
@Name("ticketWorking")
public class TicketWorkingAction implements TicketWorking {

 @Logger
 Log log;

 @PersistenceContext(type=PersistenceContextType.EXTENDED)
 EntityManager em;

 @Out(required=false, scope=ScopeType.CONVERSATION)
 Ticket ticket;

 @In(required=false)
 Long ticketId;

 @In(required = false)
 String name;

 @In(required = false)
 String description;

 @In
 User authUser;

 @StartTask
 //@BeginTask -- i tried either or
 public String viewTask() {
 log.info("ticket working - view task - #{ticketId}");
 ticket = (Ticket) em.find(Ticket.class, ticketId);
 log.info("ticket found - #{ticket}");
 return "/ticket_work.xhtml";
 }

 @EndTask(transition="next")
 public String save() {
 log.info("ticket working - save");
 saveChange();

 return "/ticket_list.xhtml";
 }

 @EndTask//(transition="next")
 public String finished() {
 log.info("ticket working - finished");
 saveChange();

 return "/ticket_list.xhtml";
 }

 private void saveChange() {
 // TODO change the owner?

 TicketChange tChange = new TicketChange();
 tChange.setDescription(description);
 tChange.setUser(authUser);
 em.persist(tChange);
 }

 @Remove
 @Destroy
 public void destroy() {

 }
}

The JSF page ->

<f:view>
 <h:form>
 Description - <h:inputText value="#{description}"/><br/>

 <h:commandButton value="Save" action="#{ticketWorking.save}"/><br/>
 <h:commandButton value="Save and Send to Approval" action="#{ticketWorking.finished}"/><br/>

 <p>
 <s:link value="View Tickets" action="/ticket_list.xhtml"/><br/>
 </p>
 </h:form>
</f:view>

.... i am hoping its just something stupid. But any ideas could help

Btw i have the two methods because I was trying both ways.

FWIW Ticket is an Entity Bean.

[pmuir]

@EndTask(transition="next")
 public String save() {
 log.info("ticket working - save");
 saveChange();

 return "/ticket_list.xhtml";
 }

This is right. Have you checked that the method is being called, and completing without exception?

[mdarr]

I should have been more specific that's the problem its NOT calling it for some reason.

IF i comment out the the @EndTask ... it will call the method just fine. Of course then it will not end the task if i do. So i know it is not a problem of finding hte bean. But for some reason put that @EndTask in front .... and it doesnt work.

Just guessing:

Could it be because of attribute "end-task" in

<task-node name="working" end-tasks="true">

?

According to jBPM docs this is ending tasks automatically. Just try to omit "end-tasks" attribute.

[mdarr]

I tried omiting end-tasks and changing end-tasks to false and it still did not work.

I did some more debugging and have an idea on the problem.

Basically there is no task available and thats why it never executes the method.

So i am assuming the long running conversation is no more. But i am not sure why that would be.
