[news.eclipse.modeling.gmt.amw] Re: AMW to ATL

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

hi,

I think I got it now. We were thinking about versions of Eclipse, ATL, AMW, etc., but the 
problem may be related to these properties you mentioned.

We had a similar problem with "Key2NestedAMW2ATL" example: we didn't set up the 
"IsRefining" and "IsAbstract" properties, because they were not mandatory. But we changed 
the metamodel (a while ago) and they are mandatory. There was an .ecore file, but the .atl 
was either empty, either only with the heading. In the examples I usually set these 
properties to "false", and "isUnique" I don't set it, because they are related to lazy rules.

About the versions (to be sure), the (3.1.0, 2.1.0 and January versions of ATL, AMW and 
AM3) should work. The latest from the sources (as you tried), need Eclipse 3.2.1 and EMF 
2.2.1.

Regards,

Marcos.
