[rules-users] dsl mapping for and/or
hi is it possible to have a dsl providing users to write somthing like :
bool1 AND bool2 OR (bool4 AND bool5)
I tried to use eval and the mapping bellow :
TELS QUE {v1} ET ({v2} OU {v3}) -- eval({v1} ({v2} || {v3}));
In my drl I have this condition :TELS QUE EA001 ET ( N OU F )
But it seems not working :
testFromMessage/Rule_indicateur___facturer_0.java (15:551) : Syntax
error
on token OU, invalid AssignmentOperator
testFromMessage/Rule_indicateur___facturer_0.java (15:554) : F cannot be

Re: [rules-users] Test for null object, not null property
Edson,
Thanks for the tip. The not Building() works just fine, so long as I
don't assert the null building anyway.
I guess I was going for pure abstraction of all the rules, including
null even though deep down I knew it didn't make sense to assert a
null. The workaround is to hard code the null case like this:
private void validateGetBuilding( Building building ) throws BOException
{
// set up an exception
boException = new BOException();
// send the exception into the BRE
FactHandle boFact = businessRuleSession.insert( boException );
// send the building into the BRE
FactHandle buildingFact = null;
if( building != null )
{
buildingFact = businessRuleSession.insert( building );
}
// trigger the validate building agenda items
businessRuleSession.setFocus(validate delete or get building);
// fire
businessRuleSession.fireAllRules();
// retract items
businessRuleSession.retract(boFact);
if( buildingFact != null )
{
businessRuleSession.retract(buildingFact);
}
// check on the exception (is set in the rule)
if( boException.getCode() != null )
{
log.debug(Exception for building= + building);
String message = BOMessages.getProperty( boException.getCode() );
boException.setMessage(message);
throw boException;
}
}
With the rule in question being reconfigured to this:
rule building is null
agenda-group validate delete or get building
salience 10
when
boException : BOException()
not Building()
then
boException.setCode(BO-0008);
end
This ends up throwing the expected BOException:
08:16:26,093 DEBUG BuildingBO:288 = Exception for building=null
08:16:26,119 ERROR InCastAPI:73 = BO-0008: The building is null
Don't you just love the green bar in junit?
Thanks for you help -- really enjoying developing this app with Rules.

[rules-users] Support for MVEL-Projections in Drools
Does Drools support MVEL-Projections? If yes, could someone please illustrate an example. Projections allow you to extract elements out of a complex object graph into a single uniform collection. For example, if you have a list of User objects, and you want to get a list of the names of the users, assuming the User has a bean property for name: userNames = (name in users) Thanks, manjax23 -- View this message in context: http://www.nabble.com/Support-for-MVEL-Projections-in-Drools-tf4267685.html#a12145681 Sent from the drools - user mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] if statement in MVEL consequence
imperative logic is disable, it promotes bad rules, we don't plan to add it back in. We suggest you call a function that encapsulates this logic.

Re: [rules-users] Problems with BRMS
Hey felipe, Im going to check the standalone version to see whats going on, thanks for your feedback tks On Aug 14, 2007, at 12:27 PM, Felipe Piccolini wrote: I still have the problem in stand alone version trying to save an uploaded jar with model classes... This works fine in brms.war version in jbossAS 4.0.5. What am I doing wrong?...What can I do to solve this?...

[rules-users] Re: Independent rule evaluations
Dr. Gernot Starke gs at gernotstarke.de writes: can you detail your problem a little? I basically need to find perfect matches between two different sets of objects. If perfect matches are not found, I then create bulks of objects that are then used in combination with the individual ones to find bulk matches. If no matches are found I need then to categorize the breaks (around 10 different categorizations) and report them. The matching criteria between two object is specific enough to be fast. Once I get into break, which basically is removing some criteria components, the possible combinations increase exponentially. Bulking just compounds the problem by adding more matchable/breakable facts into memory. My bulking logic (I didnt have collect when I started with 3.0) starts a bulk looking for two diff objects with the same bulkling criteria (this is my first potential cross product since drools would produce C!/N!(C-N)! combinations). Then once the bulk for a given criteria is create I have a second rule that expands or contracts the bulks as new facts are asserted causing many different side effects. What I am basically seeing is that asserting a fact that would for instance be a perfect match, causes many of the bulking and breaking rule activations to be created and then cancelled. Considering that I am talking about tens or hundreds of thousands of facts I thought that if I could stage the activation creations I would increase processing speed. With 15K objects on each side I have been seeing something like 1 assertion per second. I am aware that this could be cross product somewhere but I have already revised the rules many many times so now I am looking for other alternatives. I am now trying to understand looking I basically need to find perfect matches between two different sets of objects. If perfect matches are not found, I then create bulks of objects that are then used in combination with the individual one to find bulk matches.
