Trying to create nested StructuredActivityNodes (SequenceNode, ConditionalNode, LoopNode), (depth > 3) I obtained the following NullPointerException (and the nested node is not created) :

Reproducible: Always

Steps to Reproduce:
1. In an activity diagram, create a SequenceNode N1
2. Create a LoopNode N2 in N1
3. Create a SequenceNode N3 in N2 : it fails.

In the current version (0.10.0), nested Structured Activity Nodes cannot be created at all (Without any exception).

The task has been renamed accordingly.

Works in the current version
