Hi,

I've integrated a gmf editor in Papyrus that does not base upon a UML model. At the moment I am updating from 0.9.6 to 0.10.0. I was able to fix all the things so that the integration works with 0.10.0, but every time a hover with the mouse over an edit part in the gmf editor I got this exception. Can I disable the navigation feature somehow?

Hi,

This edit policy is installed on all Papyrus Edit Parts (i.e. All edit parts opened in a Papyrus editor).

However, I don't really understand in which case this NPE can happen.

I will still add a simple NPE check to prevent it.

Regards,
Camille
