Caching Edit Parts possible? [message #500703]

Dear GMF folks,

When a GMF editor is open, I work on the edit parts and do some internal
stuff on them. For performance reasons I build an internal cache of the
edit parts in a HashMap.

I have the feeling, that the GMF editor sometimes refreshes all
EditParts, i.e. recreates the whole edit part hierarchy from the domain
model. I have this feeling, because sometimes my internal cache is
completely outdated and does not contain any of the current EPs of the
editor.

Can someone give me a hint, when and why these refreshes of edit parts
are done?

Hello Hauke,

You can use GraphicalViewer.getEditPartRegistry().get(view) to get EditPart
instance having notation model one, so you probably can remove custom cache
and use one from gef.
