Re: [mdt-papyrus.dev] Write access on applied Profile (ReadOnlyHandler m

[Cedric Dumoulin <cedric.dumoulin@xxxxxxx>]

  Hi,

  The proposed enhancement takes into account the frozen Ecore version 
of the Profile. It automatically re-apply the Profile, and so regenerate 
the static version.
  Some experiments have shown that this work. But now I am stuck with 
the readonly problem.

  Regards,
    Cedric
