Hey guys,

Is there any timeframe attached to when 4.0.1 will be out? I am working on a project that is using quite a bit of static functions in the LHS, I believe there is bugs that was mentioned before with MVEL concerning this.

Regards

Juan

    If it is not firing, it is a bug. Although we fixed several related bugs for 4.0.1 that shall be out soon.
    If you can provide a test case and open a Jira, I can do some further debugging. Essentially, the difference between the rules is that expression in the first rule is being converted into an MVEL expression, because of the nested accessors, while the second is a pure drools expression.

Folks,

Using 4.0 GA.

Need to have a rule that executes when there exists a Supplier with business status == active. I am inserting Supplier in working memory.

I did that :

rule #1

when

exists( Supplier( businessStatus.status.isActive == true ) )

then

System.out.println("FOUND!!!!");

End

But it doesn't work….

Although other rules like if there is supplier with name = "SOME NAME" – they work :

rule #2

when

exists( Supplier( name == "SOME NAME" ) )

then

System.out.println("FOUND!!!!");

End

Any ideas how to make rule #1 work…. ?

Thanks,

Sergey
