BPMN2 simulation step into and out of child models (composit models)

[rghubert]

Cross post from https://stackoverflow.com/questions/52931100/sparx-enterprise-architect-bpmn-simulation-step-into-and-out-of-child-models-co

In BPMN 2, if I create a context-menu=>new child diagram=>Composite Structure Diagram within the same package, then the simulation navigates to it and also back out to the parent.

However, when I link to a BPMN2 diagram in another package via context-menu=>new child diagram=>select Componsite Diagram then the simulation-navigation no longer works. What am I missing?

Possible/Tips?
