[news.eclipse.modeling.gmt.amw] Re: Error while transforming AMW 2 ATL

[Marcos Didonet Del Fabro <mddfabro@xxxxxxx>]

Hello,

I managed to reproduce the same error here. I used a bundle of ATL+AM3 
(Feb 16, 07) and AMW from March 30, 2007.

I didn't discover why it happens, though I think it is related to the 
serialization of the models.

However, the transformation still produced an ATL model as output 
(ATL-model.ecore). I was able to extract it into the textual ATL file 
(ATL-model.atl).
