[jboss-user] [JBoss jBPM] - Re: jBPM4 - Task Escalation with Timer

[djcye]

i studied the docs and the only way to assign tasks is through the TaskService or the assignmentHandler. i tried to put the assignmenthandler inside a "timeout event" section but that isnt valide.

well i also tried to use the eventhandler approach (to use the TaskService) without success. All TaskQuerys result in 0. Testet the same TaskQuery from a EJB Web-Service and it showed more than 0, so its not the querys fault ^^". perhaps this kind of operations is not supported from inside the handlers.

so the only option i see is to put the

  | InitialContext ctx = new InitialContext();
  | ProcessEngine processEngine =(ProcessEngine)ctx.lookup("java:/ProcessEngine");
  | TaskService taskService = processEngine.getTaskService();
  | TaskQuery b = taskService.createTaskQuery();
  | b.assignee("peter");
  | List<Task> c = b.list();
  | System.out.println(c.size());
  | 

one additional question: if i use a transition timer inside a task node and the timer fires. will the task be completed / deleted ? 

i tried to figure it out on the server. after the timer fires the task still remains in the assigned groups but cant be claimed anymore. exceptions when trying to claim:

16:17:22,953 INFO  [DefaultCommandService] exception while executing command org.jbpm.pvm.internal.cmd.AssignTaskCm
  | d at 7aba71
  | org.jbpm.api.JbpmException: task 55 does not exist

actualy task 55 realy doesnt exist. the taskid i try to claim is 59 O_o

and

16:27:02,218 ERROR [[Resteasy]] Servlet.service() for servlet Resteasy threw exception
  | org.jboss.resteasy.spi.UnhandledException: java.lang.RuntimeException: Unexpected invocation exception: null

and 

Caused by: org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [org.jbpm.pvm.internal.m
  | odel.ExecutionImpl#75]

well i think the task gets deleted. but i am not sure.
