Hi!! I'have a big problem..
First at all... sorry if my english is not good..

I need to hide a node when I double click on one other node associated
with it.
If i change the EditPart.getFigure.setVisible value I obtain what I want
but I need to save the changes.. (when I reopen the diagram I need that
the node is still not visible) and with this method I can't do that. There
is a way to notify the visibility change?

I try also with a command that change the property of the EditPart
(ChangeValueRequest or something like that) but with this method the node
that I hide disappears also in the children collection of the other node
and I don't want this!!!

Please help me.. Thanks

Hi,
Try to obtain the view from editpart and perform the hide operation inside
command class
View hostView = (View)editPart.getModel();
hostView.setVisible(false);

Thanks but also with this method GMF delete the reference to the child
EditPart and I can't show again the figure because the child collection of
my parent editpart is empty!!

Hi,
If you want to show the child again back. Then go one level up obtain the
view from the parent editpart. Then obtain the child views and filter out
and obtain the view to be unhidden.
