[news.eclipse.modeling.m2m] programatical launch of ATL transformation f

[monnet2@xxxxxxxxxxxx (Xavier Monnet)]

Hello,

I am trying to do a programatical launch of an ATL transformation from 
Ecore to Ecore.

And I am getting this error message:

When I did the ATL transformation in Eclipse, I get a similar error and I 
solved it by using the option "is a metametamodel" in the Run 
Configuration of the ATL Eclipse plugin. 

How can I set this option to the model handler? Is there any specific 
model handler for Ecore to Ecore transformations?

Thank you in advance for your help.
