Re: [rules-users] Upgrading from 3.x to 4.0.7

Hi - I'm upgrading a large base of rules from 3.x to 4.0.7. However there seem to be a few semantic differences. I have rules like the below in a few places: rule "All items should have a unique external id" when new_item : Item( exId : externalId ) old_item : Item( externalId == exId ) then LOG.warn( "DUPE Detected: new:" + new_item + " old:" + old_item ); retract( new_item ); end And this all worked fine because 3.x would never assign the same object to both new_item and old_item. I know my new/old seem arbitary - but I'm just getting down to the minimal reproducing case. 4.x now will assign one instance of an object to both new_item and old_item. Is there any way to disable this behaviour? thanks, -Tom _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
