sequencing by business logic/ classcastexception in consequence
by Joost de Vries
Hi Michael,
The list is defined in terms of the superclass that both classes share. And
the previous and next methods both have the superclass as the return type.
So I'd expect
PreventieveInsluitingsTitel(previous==secondPosition [...]
to evaluate to
<instance of superclass> == <instance of subclass>
I'd expect this check to just fail when the objectreferences do not refer to
the same object. Not to cause a classcastexception.
But the exception is thrown in the consequence part of the rule during an
invocation of modify( ).....
So I'm not sure why this construction would be wrong and what would be the
right way to do it.
oh, by the way; sorry for the dutch classnames. That must make the problem
harder to understand. In fact it's about convictions and the subclasses are
types of convictions.
regards,
Joost

sequencing by business logic/ classcastexception in consequence
by Joost de Vries
Hi,
I'm new to jBoss Rules and I'm hitting a few snags. I appreciate your
insight.
Among other things I want to use business rules to compute the right
sequence of actions that conforms to legal business rules.
The only way I could think of to implement this using rules is to use
rewriting production rules similar to:
input: ACCAAAC
rule: CA -> AC
My first question is: what other ways are there to compute a sequence that
conforms to sequencing business rules?
My second question concerns the nullpointerexceptions and
classcastexceptions I'm encountering in my rules.
I've got a sequence of C's who are either B's or A's. I.e. C is the common
superclass. This superclass has the methods:
public C getPrevious();
public C getNext();
Actually it's in dutch so it's
public class Straf extends InsluitingsTitel {}
and
public class PreventieveInsluitingsTitel extends InsluitingsTitel {}
and
public abstract class InsluitingsTitel{
public C getPrevious();
public C getNext();
}
The rule is as follows:
rule "WSV 68.1"
when
// any PreventieveInsluitingsTitel should precede all Straf
secondPosition: Straf ( firstPosition: previous )
thirdPosition: PreventieveInsluitingsTitel(previous==secondPosition,
fourthPosition:next)
then
System.out.println( "switching wsv 68.1 "+secondPosition+"
"+thirdPosition);
thirdPosition.switchWithPrevious();
if(firstPosition!=null){
modify(firstPosition);
}
modify( secondPosition);
modify( thirdPosition);
if(fourthPosition!=null){
//in the next statement a classcastexception is thrown
modify(fourthPosition);
}
end
results in a classcastexception. The sequence is at that moment { Straf,
Straf, PreventieveInsluitingsTitel, Straf } and the middle two items are
matched by the LHS secondPosition and thirdPosition.
Here's the stacktrace.

Beginner looking for help with some Drools/Rule concepts
by Kabe
Hi, i've been attempting to use Drools/JBossRules (3.0.5) in a project i'm
working on and i've run into a few issues that i could use some help with.
For the most part i'm struggling with design patterns on how to structure my
facts and my programs object model.
I'm struggling a bit with how to properly introduce my object model into the
working memory. For example, lets say i have an object model such as:
Car(
Engine(
boolean : running
) : engine,
color,
Door(
boolean : open
)[]:doors
)[] : cars
This would model a list of cars and some fields such as engine, color, and
doors. Now how would i create a rule that would return every car with a
running engine? I can't seem to figure out how to correctly reference a
field of a field of a fact. i would want to do something like Car(
engine.running == true ) or Car( Engine( running == true ) ) but that
doesn't work. I can't make the Engine itself a fact because it has to be a
field of the Car, and i can't give the car a field that holds the state of
the engine because then that breaks encapsulation and makes the Car class
very bloated with the state of all of its many components.
Is there a way to do this correctly? i could use a real messy predicate or
something like this:
$car : Car()
eval( isCarRunning( $car ) )
But then what is the point of using Rete? doesn't that just equate down to
about the same amount of work if i just put this in some standard java
if/else code?
Thanks for the help,
....

Re: [rules-users] bounded variable...
by Joel G. Rivera-González
well our product is very mature and its been ruining drools for quite some time...
so i need to change the versions to see if it give better performance and memory usage...
and while i need to rewrite the rules, the results need to be the same...
remember the main rule lib is about 2.4 megs but we have several other smaller rule files...so i can say we have over 3 megs of xml rules...
and thats BIG...
now the big question...
when is the next release scheduled?
we i'll be able to use the or the right way?
i'm inclined to wait for next version...

Subject: Re: [rules-users] bounded variable...
Joel,
In 3.0.x, you can not use inside a predicate, any other variable bound
in the same pattern, besides the one that is bound to the predicate. To
do that, you need to use an eval:
rule "modem_warranty_menu"
when
megaTO:MegaTransferObject(other_EffectiveOrderTypeDsl ==
Constants.NEW_COMPLETED_ORDER_TYPE, at:other_IsAdaAltaTraslado,
nm:orders_NewModem )
eval( nm.equals(Constants.FLAG_YES) ||
(nm.equals(Constants.FLAG_NO) && at.equals(Constants.FLAG_YES)) )
then
menu.add(new String[]{Constants.SERVICE_ASSURANCE_TREE_MENU_DSL,
Constants.SERVICE_ASSURANCE_MENU_WARRANTY});
end
Seems you are doing great in pushing the limitations of drools 3.0. :)
This is also a limitation that is already solved in trunk for the
next release.

bounded variable...
by Joel G. Rivera-González
rule "modem_warranty_menu"
when
megaTO:MegaTransferObject(other_EffectiveOrderTypeDsl == Constants.NEW_COMPLETED_ORDER_TYPE,
at:other_IsAdaAltaTraslado, nm:orders_NewModem -> (nm.equals(Constants.FLAG_YES) || (nm.equals(Constants.FLAG_NO) && at.equals(Constants.FLAG_YES))))
then

end
this rule cause a compilation error...
the reason appears to be at:other_IsAdaAltaTraslado,
why it doesnt allow me to have 2 bounded variables on the same rule?

Anti-rules and infinate loops
by Myles Goodhue
Hello,
I have a set of rules that determine a target date for a business object
based on which rule criteria the object matches. When the business
object is asserted, the target date field may or may not be null. My
problem is if the business object does not match any of the rules I
would like the target date set to null and since there are multiple rule
possibly affecting the same object I would rather not create an
"anti-rule" for each rule which sets the target date to null.
I've tried creating a rule with a higher salience value which sets the
target date to null, if it is not already, and modifies the object but
when the object matches another rule and modifies the object again it
goes into an infinite loop. I could probably set the target date to
null before asserting it into the rule engine but I was hoping to keep
it self contained.
Here's an example of what I'm talking about:
rule "Pre"
salience 10
no-loop true
when
$bo : MyObject( targetDate != null )
then
Date tmp = null;
$bo.setTargetDate(tmp);
modify($bo);
end
rule "Post a"
no-loop true
when
$bo : MyObject( targetDate == null, criteriaMatches == "A")
$someDate : ThisDateObject();
then
$bo.setTargetDate($someDate);
modify($bo);
end
rule "Post b"
no-loop true
when
$bo : MyObject( targetDate == null, criteriaMatches == "B" )
$someDate : ThatDateObject();
then
$bo.setTargetDate($someDate);
modify($bo);
end
etc...
I'm pretty sure there is a simple answer but it just won't come to me.
Thanks for any help.

Re: [rules-users] About String..."==" same as ".equals"?
by Joel G. Rivera-González
ok...
there is something wrong (in my opinion) with the rule parser..
this is a rule i would write...
rule "change_bandwidth_menu"
when
megaTO:MegaTransferObject(other_EffectiveOrderTypeDsl == Constants.NEW_COMPLETED_ORDER_TYPE,
other_HasBandwidthChangeOrderOpen == false,
eotp:other_EffectiveOrderTypePos ->(
eotp == null
))
then
menu.add(new String[]{Constants.SERVICE_ASSURANCE_TREE_MENU_DSL, Constants.SERVICE_ASSURANCE_MENU_CHANGE_BANDWIDTH});
end
this rule doesnt compile...
now this rule does compile
rule "change_bandwidth_menu"
when
megaTO:MegaTransferObject(other_EffectiveOrderTypeDsl == Constants.NEW_COMPLETED_ORDER_TYPE,
other_HasBandwidthChangeOrderOpen == false,
eotp:other_EffectiveOrderTypePos ->(eotp == null))
then
menu.add(new String[]{Constants.SERVICE_ASSURANCE_TREE_MENU_DSL, Constants.SERVICE_ASSURANCE_MENU_CHANGE_BANDWIDTH});
end
same rule...but the italic text is on a single line on the last one instead of two lines...

Joel,
No. Your mistake is on the mapping of objects x patterns. Let me show
you an example:
If you write a rule like this:
rule "expensive muzzarela"
when
Cheese( type == "muzzarela", price > 50 )
then
// so something
end
You are saying the engine: "- match each SINGLE instance of Cheese
that is BOTH type == "muzzarela" AND whose price is greater than 50".
If you write a rule like this:
rule "one muzzarela and one expensive cheese"
when
Cheese( type == "muzzarela" )
Cheese( price > 50 )
then
// do something
end
You are saying the engine: "- match each PAIR of Cheese instances,
where the FIRST instance is of type == "muzzarela" and the SECOND
instance is of any cheese that has price greater than 50".
Do you see the difference?
So, if you do:
workingMemory.assert( new Cheese("muzzarela", 70) );
workingMemory.fireAllRules();
Only the first rule will fire, because the second rule requires 2
objects, one matching each constraint.
If you do:
workingMemory.assert( new Cheese("muzzarela", 10) );
workingMemory.assert( new Cheese("brie", 70) );
workingMemory.fireAllRules();
Only the second rule will fire, because the first rule requires that
a single object match BOTH constraints.
So, the above has nothing to do with variable bindings, but to make
clear, you can bind variables to each of the patterns you write, but you
can't use the same variable name for different patterns as each pattern
will match a different object.
Also, please note that top level AND operator is optional as it is
already implicitly handled. So, the bellow rule is IDENTICAL to the one
I wrote above:
rule "one muzzarela and one expensive cheese"
when
Cheese( type == "muzzarela" ) AND
Cheese( price > 50 )
then
// do something
end
I hope it clarified things a little bit. Let me know if you still
have questions.

// do something
end
You are saying the engine: "- match each PAIR of Cheese instances,
where the FIRST instance is of type == "muzzarela" and the SECOND

Do you see the difference?
So, if you do:

workingMemory.fireAllRules();
Only the first rule will fire, because the second rule requires 2

workingMemory.assert( new Cheese("brie", 70) );

Subject: Re: [rules-users] About String..."==" same as ".equals"?
Joel,
No. Your mistake is on the mapping of objects x patterns. Let me show
you an example:
If you write a rule like this:
rule "expensive muzzarela"
when
Cheese( type == "muzzarela", price > 50 )
then
// so something
end
You are saying the engine: "- match each SINGLE instance of Cheese
that is BOTH type == "muzzarela" AND whose price is greater than 50".
If you write a rule like this:
rule "one muzzarela and one expensive cheese"
when
Cheese( type == "muzzarela" )
Cheese( price > 50 )
then
// do something
end
You are saying the engine: "- match each PAIR of Cheese instances,
where the FIRST instance is of type == "muzzarela" and the SECOND
instance is of any cheese that has price greater than 50".
Do you see the difference?
So, if you do:
workingMemory.assert( new Cheese("muzzarela", 70) );
workingMemory.fireAllRules();
Only the first rule will fire, because the second rule requires 2
objects, one matching each constraint.
If you do:
workingMemory.assert( new Cheese("muzzarela", 10) );
workingMemory.assert( new Cheese("brie", 70) );
workingMemory.fireAllRules();
Only the second rule will fire, because the first rule requires that
a single object match BOTH constraints.
So, the above has nothing to do with variable bindings, but to make
clear, you can bind variables to each of the patterns you write, but you
can't use the same variable name for different patterns as each pattern
will match a different object.
Also, please note that top level AND operator is optional as it is
already implicitly handled. So, the bellow rule is IDENTICAL to the one
I wrote above:
rule "one muzzarela and one expensive cheese"
when
Cheese( type == "muzzarela" ) AND
Cheese( price > 50 )
then
// do something
end
I hope it clarified things a little bit. Let me know if you still
have questions.
