Re: [rules-users] Drools firing wrong rules

[Edson Tirelli]

   It is not possible to know, looking only at the screenshots that you
sent, what is the problem. Are the values null at the time you insert them
into the session? If you modify them after inserting them into the session,
are you properly notifying the engine?

Yes that's right.. can you share some tests to see how you are inserting the
facts?

Hi everyone,
I have a couple of rules, I just want to show a message when
one of the
fields is null and heres my code:

21. |   rule 'rule1'
22. |   salience 9990
23. |   when
24. |   Cuscar(bgm.size > 0 && bgm[0].c1001== null );
25. |   then
26. |   logger.log("Rule 1 activated");
27. |
28. |   end
29. |
30. |   rule 'rule2'
31. |   salience 9970
32. |   when
33. |   Cuscar(bgm.size > 0 && bgm[0].c1004== null );
34. |   then
35. |   logger.log("Rule 2 activated");
36. |
37. |   end

And here's the result:

Scenario #1

http://drools.46999.n3.nabble.com/file/n3160376/debug2.jpg
with this values when I call fire all rules I dont get any
message (its ok
because none of the elements is null)

Scenario #2
http://drools.46999.n3.nabble.com/file/n3160376/debug1.jpg

with this values when I call fire all rules both rules are
fired so i get
both messages "Rule 1 activated" and "Rule 2 activated"
(Incorrect - it
should only fire rule number 1 cause only the element c1001 is
null)

Scenario #3
http://drools.46999.n3.nabble.com/file/n3160376/debug3.jpg

with this values when I call fire all rules I dont get any message
(Incorrect - it should activate rule number 2)

This is my model:

http://drools.46999.n3.nabble.com/file/n3160376/rules-drools-model-1.0.0-SNAPSHOT-jar-with-dependencies.jar
rules-drools-model-1.0.0-SNAPSHOT-jar-with-dependencies.jar



Can anybody help me please?, I dont know what am I doing
wrong, thank you
very much :)

Re: [rules-users] Drools firing wrong rules

[Wolfgang Laun]

It's indeed a bug - a regression from 5.1.1.

Depending on the fact classes coming from Java or their being declared in
DRL, different error scenarios can be reproduced - see JBRULES-3129 and
JBRULES-3130, the latter being the issue reported by pamerida.

@pamerida: With 5.2.0, the only workaround that appears to cover all
contigencies is to give the mvel-ish expression a wide berth and use

eval( ((Three)list.get(0)).getA() == null )

   Ok, we will take a look at that. Thanks for reporting and verifying this.

Re: [rules-users] Drools firing wrong rules

[pamerida]

Thanks Wolfgang Laun-2...

Ive been working on the code and this

Cuscar(bgm.size > 0 , $v: bgm[0] , $v.c1001== null ); 

seems to work too, I just added the variable declaration, have no idea
why... 

Thanks everyone for your help...
