Hi Starke,

 

Thanks a lot for your inputs. Apart from being able to debug using your stuff, my main concern is that a simple declaration is making the rule not to fire. Why is that so?

I am pretty sure, when i remove that particular line the fact which is passed passes the condition.

 

The Drools documentation has a clear example which does the same.

 

Any help in this regard will highly be appreciated.

 

Thanks

Natraj

Hi Natraj,

I wrote up a few tactics to (successfully) debug rules:

http://rbs.gernotstarke.de/faq/faq/faq-devel.html

It's neither finished nor complete - but try it out...
(test both conditions with one rule for each of them,
test for the existence of the appropriate facts,
include a catchall-rule which prints all facts from wm.)

regards,
Gernot
