[jboss-user] [JBoss jBPM] - Dynamic task creation

[massimiliano_cuccia]

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
