Hi all.. I'm finding some weird behavior with Mayavi when I go to update scalars in a scalar_field source. With ImagePlaneWidgets, after using the set() or reset() methods on the source, if I say src.update_image_data = True, then I get a bunch of errors from the VTK subsystem (copied below) and the planes won't update without interaction. My initial tactic was to simply skip that step, and everything appeared fine with respect to the ImagePlaneWidgets. When I put an additional threshold and surface into that source's pipeline, then I discovered the reverse problem is true. Those objects won't update automatically unless I include the src.update_image_data = True step. How do I update the data correctly?
