[news.eclipse.modeling.m2m] Re: EMF M1 model transformation with ATL

[Marcos Didonet Del Fabro <marcos.didonet-del-fabro@xxxxxxxxxxxxxx>]

Hi Rainer,

I have also tested here (after some discussion with Freddy :) ), and it works OK with the 
files you attached.

However, the .ecore file is not the same as the metamodel you copied and pasted in the 
mail. If we copy and paste the models you put in the mail, the example doesn't work, and I 
get an error message. The element "DiskursweltObjekt" is not defined in the first 
metamodel (SOURCE MOF M2).


Regards,

Marcos.
