|Editor is dirty at openning [message #938956]

When I open a very simple Class Diagram (only one Class in it), the Papyrus editor is immediatly marked as dirty, while no change occured. Thus, in my plugin, I cannot trust the dirty state to know if there are changes or not. This phenomena appears only when stereotypes are applied on the Class. No stereotype applied, no problem !
I have investigated this issue, by adding a listener to the ResourceSet in order to print notifications when transactions are about to commit, and here is what I have observed.
For each stereotype applied, 2 notifications are repeated (see in annex the detailed print of the notifications) :
- The first is sent by the Shape representing my Class, and says that a AppliedStereotypeCompartement is added to the TRANSIENT children list.
- The second seems to be the set of a boolean in this AppliedStereotypeCompartement.
I have gone further in my investigations, and asked my little listener to throw a RollBack Exception on this event. The result is a "clean" (not dirty) Papyrus Editor that works fine.
So what is the use of this "stereotype transient stuff" added to Shapes on editor openning ? It doesn't seem to be important because they can be RollBacked without any problem. Perhaps it is a remaining part of code or a bug ?
Thanks a lot
