Hi boerse,

action in that node.
If you want to end tasks that goes to a certain transition, if I remember,
you can signal it this way (make it a signalling task so when it signals it
also ends the task)
| TaskInstance ti= executionContext.getTaskInstance();
| ti.end( transitionName );
|
I assume you want to have a task to be done by somebody, like approving an
order for example. If for some pre-determined time he does not accomplish, you
want the system to do something. Is this the correct assumption? If this is the
case, I would suggest to have only one task to keep things simple and add a
timer to cancel that task if it has elapsed some period. If you want to have
two or more users being able to carry the same task, first-come-first-serve,
then add those users in a group and specify it in the swimlane, like so:
| <swimlane name="approver">
| <assignment expression="group(groupname)"/>
| </swimlane>
|
and your task (This simply means anybody from the group can take on the
task. In this example, the "system" must be a member of the group. btw, I have
not tested the timer part but I think it should work):
| <task-node name="order" create-tasks="true">
| <timer duedate="3 business hours">
| <script>
| taskInstance.setActorId( "system" );
| taskInstance.end( "cancel" );
| </script>
| </timer>
| <task name="Approve-Order" swimlane="approver"/>
| <transition name="Approve" to="approve" />
| <transition name="Cancel" to="cancel" />
| </task-node>
|
There are many ways how to to do it, so unless I know what you want to
accomplish (real world example and not code), maybe I can add some input. If
this code does not work tell me. I did not have time to test this and I might
have forgotten some syntax, but the idea is there.
Regards,
Elmo
