Hi Benoit, please, could you detail the steps to reproduce? Thank you. /Vincent Lorenzo
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
This cannot be reproduced in the current version, I close the task
