Edson,
Thanks much, but regrettably I'm a 3.0.6 user for now. Can you offer
any tips for that version?
(Sorry to be backward looking-- I'll upgrade!)
Thanks,
Rick
Assuming you are using 4.0, just bind one and compare to the other:
rule XXX
when
Tree( $new : newNumberLeaves, oldNumberLeaves > $new )
then
// do something
end
