Hi ,

I am trying to create sirius diagram programmatically , but the following two lines are throwing java.lang.IllegalStateException exception :

RepresentationDescription repDesc = representationDescriptionInEditingDomain;
testRep = DialectManager.INSTANCE.createRepresentation(name, obj, repDesc , session, new NullProgressMonitor());

Exception :
java.lang.IllegalStateException: Cannot modify resource set without a write transaction

The Sirius editing domain is transactional, so you need to do that in a
