re-evaluate constraint [message #222986]

Hi,
I have a mapping with a node constraint.
the constraint works as expected when the editor is reloading, but it does
not affect when only a property of an element is changed.

I would expect that invoking the refresh() method of an EditPart would
trigger the re-evaluation of the constraint, but it does not seems to work
this way.

How can I invoke a re-evaluation of a constraint and cause the node to
appear\disappear ? (without reloading the editor)

I have read the thread -
http://dev.eclipse.org/newslists/news.eclipse.modeling.gmf/m sg12295.html

but it is not clear how this should be done.
Thanks
Andro

Hello Idelman,

You have to call diagram updater (CanonicalEditpolicy) to refresh diagram
content in accordance with actual model content. I suggest liostening fot
EMF notifications in corresponding EditPart and calling updater then necessary.
