Hi

The  "Model Explorer view " is open .

I have a code : 

A) Openning  a Papyrus editor

B)  Running   several times a command with a AbstractEMFOperation.execute(null,null) method's in display thread.


if you  select a other editor during step B, the NullPointerException  is throws and show in popup 

Apparently .
After a my command , the post-commit traitment , update a  "Model Explorer view " but this view don't find a papyrus editor .


Thank you

Benoit Ferrero
