[rules-users] Missing Values for a Dymanic Rule......

[Edson Tirelli]

   Nikhil,

   By your code snippet it is clear that you should not be declaring the
pattern twice in your rule. You may want to fix that.
   Also, you need to check that your code is correctly setting the values of
the adultFare and childFare attributes, because if they are not correctly
set, you will end up with a value of zero for them, that will make the rule
to always fire.

   If, after checking that, you still think it is a problem, please provide
a self contained junit test case that shows your problem and I will
investigate.
