I just loaded OmniBrowser with Refactoring engine from the menu Help-> Extending the system

Everything seems o.k. for the loading and installing
But when I tried to change the name of the Class (in the Class template of Omnibrowser) I had an error style "Undefined object >> mustBeBooleanIn:

This error does not appear if we don't load Omnibrowser and Refactoring engine.
