Hi,

 

Thanks for having fixed this.

 

Unfortunately, I think that I am facing a regression when using the same example (just use the conditions under comment "Works great"):

rule "Order"

salience 200

      when

            #Works great

            n1 : NumberTest($nb1 : nb, $index1 : index);

            n2 : NumberTest($nb2 : nb -> ($nb2.compareTo($nb1)  < 0), index > $index1);

      then

            System.out.println("Swapping " + n1 + " with " + n2);

            check(n1, n2);

            swap(n1, n2);

            modify(n1);

            modify(n2);

end                    

 

I got an error in the middle of the test (using 3.0.2), which wasn't the case with 3.0.1.

Did I made a mistake writing my rules, or is it a regression?

 

Swapping N[4] index=1 with N[3] index=2

Swapping N[3] index=1 with N[2] index=3

Swapping N[2] index=1 with N[1] index=4

Swapping N[1] index=1 with N[0] index=5

Swapping N[4] index=2 with N[1] index=5

Swapping N[2] index=4 with N[1] index=2

Shouldn't come here... false

Swapping N[3] index=3 with N[1] index=4

Swapping N[2] index=2 with N[1] index=3

Number is N[0] index=1

Number is N[1] index=2

Number is N[2] index=3

Number is N[3] index=4

Number is N[4] index=5

 

 

Thanks,

Jean-Pierre Grillon

> I face a problem (bug?): I have a condition using ?eval? which doesn?t seem to be reevaluated when objects are modified.
> The class NumberTest wraps a number (field nb) and the index (field index).
> The rule gets 2 NumberTest, the first number is greater than the second one ; and the eval condition should test that the first index is less than the second. But the rule is fired even if this condition is not fulfilled (see the check function).
