Hello guys,
i don’t know whats wrong but after current restart PolyScope seems to have a bad problem while loading its content…
The funny thing is that the error occours while starting a bundle i didn’t edit at all, so for me its relatively hard to understand then why this happens. Maybe someone of you could help.

Hopefully one of you got an idea where’s the problem. Best regards.

Ok never mind.
Seems that this problem has something to do with my try to save a Variable selected in the ProgramNode to the DataModel of the Installation Node but somehow that only gives me a bounch of errors and no success at all.
