[news.eclipse.modeling.gmf] Re: Use of ConnectionHandle to add new node

[Esteban DUGUEPEROUX <dugueperoux.esteban@xxxxxxx>]

Ok I understand that my previous message isn't so clear, I give code 
which do the work, but I don't know how to explain more clearly.
The code represents a method after user have choosen a file, the file is 
given in parameter to initialize new created model's element.

Thanks.
