I have tried to override attribute assignement override in sub rules such as

rule RuleA {
from s : IN!A (s.oclIsOfType(IN!A))
to t : OUT!A (
        attributeA <- newAA
    newAA : OUT!AA
rule RuleB extends RuleA{
from s: IN!B 
to t : OUT!B (
        attributeA <- newBB
    newBB : OUT!BB

where IN:B inherits from IN!A, OUT!B inherits from OUT!A and OUT!BB inherits from OUT!AA.

This does not work, for RuleB I have
OUT!B.attrbituteA of type OUT!AA instead of type OUT!BB.

It seems that the ATL engine, is interpreting RuleB before RuleA.

Do you have and idea to solve this problem ?

Thank you.
