[ATL] Lazy Rule Filter Not Working [message #93452]

Hi,
I have a problem with lazy rules. I am calling a lazy rule on a collection
of UML2!Class that i selected in a collection of packageableElements
(package.packagedElement collection). In the lazy rule i defined a filter
that will limit the application of the rule to the abstract classes that
are public. I wrote the following code:

...--in the managed rule i call myPublicAbstractClasses this way:
publicAbstractClasses <- s.packagedElement->select(h |
h.oclIsTypeOf(UML2!Class)) ->collect(e |
thisModule.myPublicAbstractClasses(e))

--the lazy rule:
lazy rule myPublicAbstractClasses {
from s : UML2!Class (s.isAbstract=true and s.visibility=#public)
to t : MM!PublicAbstractClass (
name <- s.name
)}

The problem is that the filter is not working, i get all the classes
inside the target property 'publicAbstractClasses'. Did i do something
wrong?!!

I found this solution, but what i would like to do is to have a lazy rule
that accepts parameters otherwise i will have hundreds of lines of
filtering in my manages rule:

--manages rule:
publicAbstractClasses <- s.packagedElement->select(h |
h.oclIsTypeOf(UML2!Class))
->select(z | z.isAbstract=true and z.visibility=#public )
->collect(e | thisModule.myClasses(e))

--lazy rule:
lazy rule myClasses {
from s : UML2!Class
to t : MM!Class (
name <- s.name
)}

I would like to write something like:

publicAbstractClasses <- s.packagedElement->collect(e |
thisModule.LazyRuleCall(params)) --params can be ('abstract','public') or
('abstract','private') and so on

Is there a solution?

I would like to know if this bug has had any development, since I'm getting the same behavior with ATL 3 in the latest Eclipse version.

Nuno
