How do I update my Ecore and GenModel after the originating model has changed?
Once you have an existing *.genmodel resource, you can right click on it to bring up the popup, or open it the editor and from the Generator main menubar item, invoke “Reload…” to walk through the same wizard steps that were used to create the *.genmodel in the first place. The wizard will remember the choices made the last time and your GenModel’s properties will be preserved during the reload processing.
