Hi Ed,
first of all, I'm probably doing something wrong with the genmodel, but
the result is the following: I create a child of some node in the tree,
then delete it, and the node doesn't disappear from the tree. If I right
click on it, the "delete" option appears disabled. The editor knows the
children is deleted, but haven't refreshed the view. Once you manually
refresh it, the node disappears. Is this a correct behaviour?
The only thing I've changed (and that's why I suspect I've done
something wrong) is changing "children" and "create child" to true, so I
can see that model element as a children in the treeview.
I have the test .ecore, the .genmodel I used and an instance model to
test it. I'm using Eclipse 3.4 RC2 and EMF 2.4.0 RC2.
Cheers,
Víctor.

Oh, I just realized It also occurs not only with children deletion, but
also when adding nodes, the first added appears correctly, subsequent
additions are not refreshed properly and doesn't show up in the tree
until manually refreshed.

Probably that means the getParent method isn't returning good results.

Does it sound correct to you? :-P

Ah yes. Likely you to specialize ItemProviderAdapter.isWrappingNeeded
to return true so that wrappers will be created for your non-containment
children. Either that, or you need to specialize getParent so it
returns the parent as it occurs in the tree you've induced.

Ed,
ahm... I think "notify" was the problem. Once set to true, the tree
get's properly refreshed. Sorry for wasting your time!
Thanks for the feedback.
Víctor.
