[jboss-jira] [JBoss JIRA] (DROOLS-519) Accumulate CollectList does not preserve the insertion order

---------------------------------

      Assignee: Davide Sottara  (was: Mark Proctor)
    Resolution: Won't Fix


The ordering crtieria was never part of the original contract, so applications should not rely on it. More specific behaviors should be implemented as different acc functions (which are pluggable) and committed

> In 5.x, acc / collectList preserves the order of insertion.
> That is, if A1, A2 and A3 are inserted, a collectList will return 1,2,3
> In 6.x, the order is reversed. That is, in the same scenario, a list
> with 3,2,1 is generated.
> While arguably a minor issue, collectList returns a list, that is an ordered
> collection. The reversal of the order breaks the compatibility of preexising
> applications (such as drools-mas)
