Hi Frank,

I think I found the problem. Actually it is a version problem with the ATL metamodel. When 
this example was done I did not take into account the 'refining mode' and the possibility 
of having abstract ATL rules. Now there are two mandatory attributes 'isAbstract' and 
'isRefining'.

For the moment, you can modify the 'AMWtoATL.atl' transformation by doing the following:

- in the rule  'rule Module', it should be like this:

atl : ATLMeta!Module (
	isRefining <- false,   -- add this line

-in the rule 'rule Root', add two bindings:

atl : ATLMeta!MatchedRule (
	isAbstract <- false,   -- new
	isRefining <- false,   -- new

- in the rule 'rule ElementLink',
add the same two bindings.

atl : ATLMeta!MatchedRule (
	isAbstract <- false,   -- new
	isRefining <- false,   -- new


I will put the the transformation with these modifications in the web site.

Regards,

Marcos.
