[rules-users] unsolved myth regarding transitive closure using insertlogical...

Hi all, I know this is kinda an old topic, but I just couldn't get it working. Here is a previous attempt using insertLogical() to handle transitive closure: http://drools-java-rules-engine.46999.n3.nabble.com/transitive-closure-td... The problem with this one is that the newly "logically inserted" object would violate its own "not exists" condition term, thus removing itself, then goes the infinite circle of insert/remove... Here is a post that deals with transitive closure using "insert", but it doesn't handle object removal correctly: http://drools-java-rules-engine.46999.n3.nabble.com/one-question-about-Tr... To me, using insertLogical is attractive because it doesn't require me to write specific rules to handle object removal. Is there a trick that I can use to actually implement transitive closure with insertLogical? Thanks a lot! -Simon
