[jboss-jira] [JBoss JIRA] Commented: (JBRULES-1155) In Decision Table actions, cannot reference variables that were not referenced in LHS

Mark Proctor commented on JBRULES-1155:
---------------------------------------

forget decision tables for the moment and show me how this would be done in standard DRL. How can the consequence bind to some data matched on the LHS? how does it know which pattern or which field?

> If I use a decision table to build rules for my application, there doesn't appear to be a way to store an answer on a variable that wasn't referenced in the LHS of the rule. This is because the reference to the object that must be built can only be defined in the LHS.
> I would like to be able to directly reference these "catcher" objects from the action to store the result even if they were not needed as part of the LHS.
