Hi all!
I am struggling for days with a problem concerning element deletion and a
phamatm node keeping reference to the deleted element. Here my problem in
more detail hoping someone have a hint to solve it:
1)I have a model: Root<>---As<>---Bs<>---Cs<>---Ds, Root<>---Es ,
E<----->D
2)I created an editor where I display As and Bs contaiment via compartment

Hi,
I had a similar issue which involved two different resources.
Are the elements you list below in the same or different resources ?
Also how do you do the deletion ? (using EcoreUtil.delete or something else
?)
thanks

They are in the same diagram file but as i said through a diagram
partition.

I do the deletion in the diagram via "delete" key or "delete from model"
and I have the same result.
In fact, I created a command to close(if opened) and supress the
sub-diagram that represents the B node from the resource. A sort of clean
up of the GMFResource.
Then I tried to use the same mechanism for the Cs children present in B
diagram to have acess to the D element and to easy the reuse because I had
other sub diagrams and phatom nodes.
I found that this solution is no use because the editparts instances are
accessible only if the concerned diagram editor is opened.
I tried to send a deleteRequest to the model trying to use the
DeleteCommand mechanism but i failed. I think because the diagram did not
share the same editing domain with the model tree-editor.
I did not try EcoreUtil.delete but I think it will only remove the
references from the GMFResource without using a command and then without
updating the model.
But I will give it a try.
