Hi all, If I add a callback to a node like this: import maya.api.OpenMaya as om mayaCallbackID = om.MNodeMessage.addAttributeChangedCallback(mObj, myFunc)
and then later I do om.MMessage.removeCallback(mayaCallbackID) I get the error #RuntimeError: (kInvalidParameter): No element at given index If I look at the callbacks on the node like this: print om.MMessage.nodeCallbacks(mObj) I can see that mayaCallbackID is among the IDs on the node. I see examples of MNodeMessage being removed like this in the API examples, eg http://help.autodesk.com/view/MAYAUL/2015/ENU/?guid=__cpp_ref_hw_unlit_shader_2_node_monitor_8cpp_example_html but it doesn't seem to work in Python. Has anyone done this successfully? What am I doing wrong? Thanks, Boon -- You received this message because you are subscribed to the Google Groups "Python Programming for Autodesk Maya" group.
