Dear all, I've found out that the error comes from the fact of using a PN director as an opaque director inside a worflow managed by another PN director! Somehow this problem is related to "Director compatibility" issue.
So I've decided to simplify the workflow and use a model workflow just in order someone can find a trick to run it succesfully. The main idea is ?How can we can continue the execution of a workflow after the execution of an opaque composite actors with PN director inside when the overall director is an PN one? In the attached example (exampleCompositeActors.xml), I cannot get a "Execution finished" but the Kepler shows the "wrapping up" signal or alternatively a permament "executing" signal although apparently nothing is running (only finished partly). No error message is displayed! Which worflow design I should adopt? What Am I doing wrong? How Can I pursue my aim to execute PN composite actors sequentially? All help appreciated!
