Hi,

I want to validate my model after each change to it. Adding elements, changing attributes etc. I use the following code to start the validation:

ValidateAction.runValidation(notationView);


When I place this code in handleNotificationEvent of EditParts I get the following exception:

Quote:
Caused by: java.lang.IllegalStateException: Cannot open an operation while one is already open


Where can I start validation without getting an exception?

Ralph
