(1) -> yes because when I print the value, the value is correct ( = 2 ). Not the eval.
(2) -> yes, true. My list is in alphabtic mode...
(3) -> Every test I make made the wrong result

eval( $patient.getNbFactRisque() == 0)
or $patient : PatientDto( nbFactRisque == 0 ) ...
---> Why does those test are true dispite nbFactRisque = 2 ????

It works fine when I run x time drools (one call for one rule) but it doesn't work when I run one time with a List of rules.

Can you tell me the right mailing list for those problems ?

Please do not use this list for simple questions - it is reserved for discussion Drools development itself.

(1) Did you inform the Drools engine about incrementing nbFactRisque?
(2) There is no such thing as "alphabetic mode" for rule execution.
(3) Why do you use eval when you can test the fact field?

Hi,

I've got an other problem with an eval function.
I will try to discribe the path to the error.

I've got a repository where some people can put rules with .drl extension.
My program is listing this repository and execute every rule in this repository.

At the begining, I've got a 'PatientDto' who have a property :
int nbFactRisque;
(with getters and setters)

Some rules increments this number.

In the last rule (the rules are executed in alphabetic mode) I'm testing this number like this :

rule "RisqueNormal"
    when
        $patient : PatientDto()
        eval( $patient.getNbFactRisque() == 0)
    then
        $patient.addDonnees( Constants.CLE_RISQUEPATIENT, Constants.RISQUE_NORMAL );
        System.out.println("RisqueNormal vérifié." + $patient.getNbFactRisque() + "Facteurs.");
end

Here's my problem :
The 'Then' traitement is always executed so the eval always think that $patient.getNbFactRisque() is equal to 0.
But the system.out.println() show me that $patient.getNbFactRisque() = 2 !

Here's the output : "RisqueNormal vérifié.2Facteurs.".

Perhaps I did something wrong ? Can someone help me ?
Thank you.
