Re: [rules-users] Driving License application
Can you share with us the Applicant class? because if you have something like: boolean valid; it will be automatically initialized to false, so the rule will not do anything just leave the Applicant as it is On Tue, Dec 24, 2013 at 10:05 AM, seyfullah seyfullahti...@outlook.comwrote: Hello, I am trying to implement Driving License example application in Drools Documentation Versio 6.0.0.0 Final.

I expected that it is true. I think there is something wrong. Do you have any idea about this problem?

Re: [rules-users] Driving License application
So, if you don't touch in some way the boolean valid, value in your rules
or in your java code it will be false not true.

Re: [rules-users] Driving License application
If you have a property (such as valid) that has N possible values (2
in this case) you should have at least N-1 rules, setting values 1 to
N-1 (as you have) and a default by initialisation equal to the N-th
value (which is missing from your code).
Alternatively, consider using N rules, one for each possible value,
and then you don't have to worry about initialisation.
