[rules-users] "extends" in rules

[Matt Wixson]

Hello,

I am encountering the same problem described in the previous posting but
did not see a response.   Is there a workaround or fix for this issue?

The error is: "Unable to find declaration in list while generating the
consequence invoker" when any variable from the parent is used in the
child rule's Consequence.

Thanks,
Matt
