I use the synchronize function in gmfgen.
I know canonical behavior means the View will exist only if the semantic
element (model element) exist, but the view was not deleted as soon as
the semantic element is gone.
It remains in the diagram until I use palette tool to create another view on
the Editor.
How can I delete the view instantly?
Is it means that if the editor was refreshed and the view without element
will gone. If so , how can I refresh the Editor?

You will need to check that your canonical edit policy is refreshing
when you delete the semantic element, which does not seem to be the case
based on what you are describing here, the canonical edit policy listen
by default to the host's semantic element so it should receive the
delete event and refresh
One way to debug this is to add a break point to
CanonicalEditPolicy#handleNotificationEvent and check if it get called
or not when you delete the element, and if it get called make sure that
shouldHandleNotificationEvent(event) is returning true other wise the
event will be skipped.

Hello dzh,

Try to reopen the editor. If the view will be removed, you have to call refresh
manually (search for it in a newsgroup).

yes, it did so in the same Editor, but when the original view and shortcut
in different editors, it does not refresh.

Could you please tell me which to refresh, I use
ProcessDiagramEditPart.refresh(), and debug through it . Finally, I found
that it did not refresh views, so, would you please tell me which one I
should refresh? call the refresh method?

Hello dzh,

ProcessDiagramCanonicalEditPolicy should be generated in addition. This EditPolicy
is responsible for updating the diagram. I suggest you to call “refresh”
method of this EdtiPolicy. This method will be automatically called on opening
editor from the “activate” method of this Editpolicy.
