[EMFForms] EKeys on EReference validation constrain only fired on initial AddCommand [message #1453883]

Hi there,

how can I use EKeys on EReferences properly with EMFForms?

When I setup an EKey on an EReference to restrict duplicate EAttribute values I'm seeing the validation rule firstly fired when I'm reloading the ECPSWTView or if I use internal actions of RefernenceMultiControl (Delete, Up, Down).

I see in MultiContol an IListChangeListener which unfortunately does not fire the validation. So i see no hook other than changing databindings - where i have no clue how to setup it for this case.

Is there a different solution?

Thanks in advance!
Phil

Hi,

does it work if you programatically change the model instance?
The UI will just create Commands and run them on the model. There should
be no need for any other trigger, because the validation service listens
for changes. Could you provide a test case to reproduce this behavior?

best regards

Jonas
