Hi,
I try to change the container of an EObject. The EMF Command that does so
is a Compound one that removes (RemoveCommand) the object from the list of
its container (and the cross reference is also deleted) and then a set the
new Container to my object (SetCommand).
While notifying the remove, when trying to remove my object from
StoreResource.loadedObjects, it does a loadedObjects.remove(myObject) that
calls the equals of my object and you can see what happens.
Isn't it possible to change the container of an object in Teneo/JPox
context ?
Should I override the commands ? And How ? My object will still be without
container at a given time, am I right ?
Thx
