Re: [rules-users] irrational behaviour by drools engine

I still don't fully understand what you are trying to do, but could you maybe try inserting each object in your hashmap as a fact rather than having a global hashmap. Your rule would then look something like: WHEN EncapsulatingObject($id : id) EncapsulatingObject(id == $id) THEN Do something.. END This rule simply checks if there are two encapsulatingObjects with the same id. -- View this message in context: http://drools.46999.n3.nabble.com/irrational-behaviour-by-drools-engine-t...
