Michael Neale commented on JBRULES-1155:
----------------------------------------

you have to have a variable in a rule to reference it. 

Each row is a rule, so if you have a rule that is missing a variable declaration on the LHS, there is no way that can work or make sense. 

If you use globals, you can access the global value to store results - I think that is what you want.

> 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.
