Unfortunately this one is not working http://developer.qt.nokia.com/wiki/Selectable_list_of_Python_objects_in_QML with ubuntu 10.10. Result is emty window and message: ile:///home/user/PythonList.qml:18: TypeError: Result of expression 'model.thing' [undefined] is not an object. can this be fixed? Niki -- | (\_/) This is Bunny.
