Hello Cajus,
really looks like you said, rootNode is null. With your push into a
children array you change the length of a model node. So you could
check the __changeModelChildren method, which calls the
__updateTreeChildren method. This method fetches the reference to the
tree node from an internal store of nodes called __childrenRef.
Perhaps the nodes array is not stored correctly. You should can have a
look at that first.
But as christian said, it would be best for us to have a code snippet
which demonstrates the error so i can get into detail for myself and
fix the bug in the tree controller right away. Because this sounds
like a bug in the tree controller to me.
Best,
Martin
