Hiho!
I've an application which loads a tree model to a TreeController, connected to
a Tree and a couple of other thingies in the GUI. This works fine - so far.
Now, I'm going to add a new node like shown in the TreeController demo
application using something like:
nodes[0].getChildren().push(node);
What I get, is an error in qx.data.controller.Tree.js, line 447 (444 in the
original file of qooxdoo 0.8.2, I've added debug lines in Tree.js):
rootNode.getChildren() is null
__updateTreeChildren()(qx.ui.tree.TreeFolder[undefined]
$$useinit_focusable=true $$useinit_selectable=true, td.data.model.Movie[1ac]
$$hash=1ac $$user_children=[5] $$user_uid=21)Tree.js (Linie 447)
__changeModelChildren()(qx.event.type.Data[6u] $$hash=6u _type=change
_target=[5])Tree.js (Linie 344)
dispatchEvent()([undefined, undefined, undefined, 2 more... $$hash=1ad

_target=[5], "change")Direct.js (Linie 99)

addSceneAfter()(null, td.data.model.Scene[1d8] $$hash=1d8 $$user_children=[0]
$$user_name=Horst)Model.js (Linie 48)
(?)()()
So it seems like rootNode in __updateTreeChildren: function(rootNode,
modelNode) is empty.
Can someone pass me a hint on what I can do for further debugging?
Thanks,
Cajus
