Hello Florian,
the controller needs for internal purposes a reference from every tree
folder to the corresponding model item too. So there is a more or less
internal API for accessing there reference:
treeItem.getUserData("model")
But as I said, its more or less internal. Its not documented in the
API and we can not guarantee this API to stay. But i don't think we
will change that for a while and there will always be a reference to
the model. So you don't need to worry about using it.
Regards,
Martin
