problem by jumping back to first view
I have implementiert 3 views in a window. The last view has a exit button. When I click the exit button, I can jump back to the first view. But then if I go on from the first view to the second view, the programm is broken, because a 1..1 cardinality of a node has been violated.
If I use exit button to leave the window, it runs good.
It seems that the 1..1 node has been initialized again.
Does any one have a idea how to handle this problem?
