Order of called observers
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Nightly build documentation of vtkObject::AddObserver() says: "When events are invoked, the observers are called in the order they were added."
However the first observer of any given priority (default 0. included) is always called last. For observers added in the following order: observer1 observer2 observer3 observer4
The actual calling order is: observer2 observer3 observer4 observer1 <- notice how the first observer is called last
