End a long running process from a page flow
I have a pageflow which calls a SSB (derivative of todo example) and when I call the done method I get IllegalStateException ... cannot call Start from a long running transaction ... call @Begin(join=true) etc...
So I changed the done method (Instead of @BeginTask(taskIdParameter="taskId") @EndTask) to use the following code:
String l = (String) org.jboss.seam.Component.getRequestParameters().get("taskId");
long tid= Long.parseLong(l);
JbpmContext jbpm = JbpmConfiguration.getInstance().createJbpmContext();
try {
TaskInstance ti = jbpm.loadTaskInstance(tid);
ti.end();
} finally {
jbpm.close();
System.out.println("Maybe the process ended!!!");
}
The first time I call the method I get the following exception. The process ends but get the nasty stack trace on the page instead of following the page flow. If I hit back and create new long running processes and stop them I dont get any errors.
If I use RequestParameter("taskId") then any other method I call on the SSB throws an exception cannot set taskId on SSB!
What am I doing wrong.
See stack trace below:
21:57:40,735 INFO [STDOUT] Async-process ended!!!
21:57:40,755 INFO [STDOUT] The process definately ended!!!
