[rules-users] error while executing business rules

You've got a problem.
Probably with what your rules are trying to do, possibly with the design of your fact class.
Use a process of elimination to work out which rule is the problem and construct the simplest example you can which causes this problem.
Then try working out if there is anything in that rule that would cause it to have problems.  If this fails then show us the rule and fact c;ass so that there is a chance we can come up with a solution rather than guessing what you may have done.

Maybe this is a hint which rule is causing the problem.

Any reason why you are using Drools 4?
Try to figure out which rule is failing and post it here.
I have never used Drools 4. I started from V5.

Try to be a little more specific. Which version of drools are you using? How your rule looks like? What are you trying to do?
