| − | Example observer invocation debugging output for a change in the MRMLScene (probably NodeAddedEvent, but shown as NoEvent because the class specific event isn't in the vtkCommand list).

| − | Note there are 67 observers registered at the MRML Scene level, many of which make changes which invoke further events. It is possible for these events to cause loops or other unexpected behavior if the programmer isn't careful. What's needed is a way to make the whole system more visible and debuggable to programmers especially in the context of a project with several distributed developers. | |
