[jboss-dev-forums] [TODO - DEVELOPMENT] - Re: Recursion in rules execution

[vivonpereira]

You have to be very careful while using the 'OR' condition (||) in the JBoss rules. 
In the documentation that the JBoss have provided, they do mention that, every OR will be treated as a seperate sub-rule by itself. 
Hence, if u have a rule like this: condition1 || condition2, then the result is going to be executed twice for the two specified conditions.

Hence, i recommend u judiciously use the or condition.
Bcoz, if u have a condition like the one below, then the result would be totally wrong:
rule test
 when
    t:Test(age > 25 || skill == 'IT')
 then
    t.setWage(t.getWage() * 1000);
end

The result should have been 1000 but it would give 1000000.

There is one more point I have noticed in ur rule file is that, there are more than one rule containing modify method. When I wrote my rule file, it did not allow me to have more than one non-exclusive rule to have a modify method.
Could u tell me, didnt it throw u any error. Since it hangs my code when it finds two rules having modify method in the same drl file.
The java code is the same as urs.
