How to end TaskInstance in a ActionHandler

freak182 Jun 4, 2009 7:33 AM

Hello,

I get the TaskInstance in ActionHandler like this:

final Collection<TaskInstance> tasks = context.getTaskMgmtInstance().getTaskInstances();

for(TaskInstance inst : tasks){
 inst.end();
 }

also i try this....

final Collection<TaskInstance> tasks = context.getTaskMgmtInstance().getTaskInstances();
 final Token token = context.getToken();

 token.signal();
 for(TaskInstance inst : tasks){

 inst.end();
 }

 context.getJbpmContext().save(token.getProcessInstance());

..the above code works but is does not route the next task to the intended transition ("to approver B").The transition was taken is the default transition. I even force the the transition with this>


private String timeoutTransition;

................................

final Collection<TaskInstance> tasks = context.getTaskMgmtInstance().getTaskInstances();
 final Token token = context.getToken();

 token.signal(timeoutTransition);
 for(TaskInstance inst : tasks){

 inst.end(timeoutTransition);
 }

 context.getJbpmContext().save(token.getProcessInstance());

the above code give me CuncurrentModificationException...any ideas?

Thanks a lot.
Cheers.

normally, if you specify a transition on a timer, the node is 'left' and that task automatically ended. So doing this in an actionhandler is not needed nor advised (at least not in a tasknode)

that's my notion of timer when attached to a 'task-node' that it will end the task node and route to the intended 'timeout transition'...i think this possible only if not using db persistence? please advise? thanks.

No, works with db persistency as well. Look at the docs for the jpdl attributes and/or look at the unittests in the source

hello,

I can get TaskInstances using this code:
final Collection<TaskInstance> tasks = context.getTaskMgmtInstance().getTaskInstances();

the above code retrieves all taskInstance in a process (it's obvious) when I use a handler. Now my question is How can i get the the specific task for which a timer handler attached to?

Thanks a lot.
Cheers.
