> AttributeError: 'NoneType' object has no attribute 'childCount' Can you show the code that is calling childCount()? In Node.row() there is a check to see that self._parent is not None before attempting to execute any operations for self._parent. From SceneGraphModel.rowCount(), parent is provided as an argument. The code that calls rowCount should make sure parent is valid, or that validation can be added to the rowCount() directly. Without having a more complete view of what you are working on it's hard to provide much more input in regards to this specific error. There are plenty of ways to handle the validation. For example, you can test type() or hasattr() before executing code that expects the special methods or attributes to be available. -- You received this message because you are subscribed to the Google Groups "Python Programming for Autodesk Maya" group.
