Originally posted by: no.spam.stop

Hello,
I'm testing the atl launcher from milan milanovic with the simple
example of the "families to persons" available on the atl web site (in
"basic examples and patterns").
I changed minor portions of code for using ecore as metametamodel
handler instead of mdr.

the steps of the transformation are :
1) inject ecore file into asmmodel with xml injector (it seems to be all
right at this step)
2) transform previous asmmodel into another asmmodel
but when i run the transformation here is the output :

-------
