Remove events are ignored [message #9784]

Hi have an EMF model and a cannonical GMF diagram attached to it. When I
add an element in the EMF model, it automatically appears in the
diagram. Unfortunately, deleting does not work. Removal events are
ignored and I have to reload the diagram to make the removed elements
disappear. Am I missing something?

Thanx
Jan

HI;
The Remove events are not ignored, they are handled already and
being forwarded by the DiagramEventBroker to the listeners
Add a break point to the notifychanged method on the canonical edit
policy, and check if this break point hits when you delete your semantic
element. This might give us some clues.
What we need to check: is refresh being called on your edit policy or not?
and if it is called is it deleting the views when you delete the semantic
elements or not ?

One Thing to keep in mind, the fact that your shapes are canonical means
they should be deleted when the element they represent is deleted this can
be achieved in 2 ways
1- since they are canonical the canonical edit policy can delete the
orphaned views
2- or in general delete and view when it element is deleted, which can be
achieved using the NotationViewDependentsAdvice

my first replay was assuming you are using the first approach, if you are
using the second approach and having troubles let us know and we will
answer your questions
