Subject: You must see this,guys...new bug? defining rules saturday night made me mad?

 

Look at this....

 

I have got a "ContractWrapper" fact inserted into WM.

 

It wraps a "Contract" object and some "enums" fields.

 

One of these fields is "upronto":

 

public class ContractWrapper extends BaseOmPersistentWithAssignedId{

Contract mycontract=null;

...

Pronto upronto = null;

...

<getters and setters....>

...

}

 

 

"upronto" is an insance of a "Pronto" java enum:

 

public enum Pronto {

N,

UNKNOWN,

Y;

}

 

"Pronto" can be : (Y, N, UNKNOWN)

 

Here is the rule which reasons over this enum:

(ofcourse I have got a Request into WM as well)

 

rule "ScorePronto"
dialect "mvel"
ruleflow-group "Scoring"
 when
     $r:Request( $mc:mainContract != null )
     $cw_p:ContractWrapper($c_w_p:mycontract == $mc, eval(upronto != Pronto.Y))

 then 
     System.out.println("Test Result: "+($cw_p.upronto == Pronto.Y))  
end

 

Any guesses for the output???

 

Well....

 

Test Result: true

 

HOW COMES???????????????????

 

I mean ... the test "eval(upronto != Pronto.Y)" returned "true".... It means that the rule

engine sees upronto <> Pronto.Y!, doesn't it??!!!!

 

So... why do I get "upronto == Pronto.Y" in the RHS????

 

What the.........&$%%&()%%$/%£....sorry....but having these

kind of problems during saturday night is not so pleaseant! 

 

T-T

 

I really hope you can help me with a  workaround to this issue.

 

Bye

 

Massi
