[jboss-user] [JBoss jBPM] - Dynamic task creation
Hi all
I have a process named Interpello that, at a certains point, executes the task
InizioInterpello.
I attached at the node-leave event an action (actionIstruttoriaInterpello).
This action have to create a task instance for a number of users (i mean a task that each
selected user must execute).
The code below (createAndAssignTask) does the work, but when the process arrives to the
task ChiusuraInterpello, it should execute the action actionChiusuraInterpello (actually
just display some outputs via println)
but it doesn't execute nothing (I can't see the output), and the execution process
doesn't step to verificaFinale.
Everything goes well if I comment all the createAndAssignTask code invocation in the
actionIstruttoriaInterpello
There is something wrong in the code below (dynamic task creation)?
thanks
I'm using jbpm 3.1.2
