Hi Matthias, This is exaclty my problem - I'm unable to reproduce this behaviour and I cannot imagine in which cases it can occur. So I have no test-cases for that. Sorry :-(
Of course, I can add a null pointer check in the code and can ask the customer to try the fix, but IMO it would be very interesting why we have a null pointer. It seems that the model was not correctly created, is it? Furthermore it would be very interesting why it only happens in a customer environment and why it is working well for me.
