Hello,
I am trying to disable resizing of my editParts.
I followed the advices in the GMF Developer's Guide - Diagram Services
Layer - How-to Guide to override getPrimaryDragEditPolicy().
However, the object can still be resized through the properties view.
How can I prevent that ?
thanks,
Tivadar

This will make the model and the view inconsistent. The data (e.g. X
coord in the model -- more precisely in the _diagram file -- ) will
change, but not updated on the screen. If the user saves the model and
loads in the next edit session, he/she will see the updated parameter,
exactly the situation I want to prevent.
