NullPointerException in TreeViewer an MacOS X #58

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem ?
1. Open an WSDL-interface with iDocIt!
2. Click on the white area below the interface-tree.

What is the expected output? What do you see instead?
iDocIt! should do nothing or at least select the last item of the tree. But it 
crashes with a NullPointerException.

I think I have fixed it, but I can not test it, because I have no Mac. Jan, 
please verify if the exception still occurs.
