[rules-users] Eval0Invoker : java.lang.NullPointerException

[Venkat]

Hi Manstis, I have tried what you said and found that, in the drools rule
file the fields and objects were not able to get by its direct name, so I
called those by calling from get methods and I am able to run the rules but
it is behaving odd now. 

I mean it is giving me the same error in my "consequence" many times and
then going to the end rule and giving me the same error twice. So I don't
know what is happening. Check out the response I get, also check the rule
file for messages
