I am trying to use ForEach component in the process flow. I need to call a
set of rules in loop. I have this subFlow created inside ForEach component.
The collection set in the working memory becomes available to the ForEach
component and infact even in subFlow the OnEntryAction and OnExitAction can
access the integerObject from the collection. But when it comes to executing
the rules, looks like the integerObject is not available to the rule and
none of the rules are executed. If I add a dummy rule without any condition
it does get executed but only once. Have anybody tried similar kind of
scenario. If yes please send me some example, as I am really stuch out here
trying to call rules in a loop.
I am attaching the souce code along with this post. Please have a look.
Here is how the ForEach flow looks like

Re: [rules-users] Object Referencing Error
In fact in your case you when condition doesn't make any sense - B will never
equal the empty string as B isn't a string.
You probable want the following:
rule "foo"
when
$a :A(Type == "Prod" , objectB == null)
then
B bobject = new B();
bobject.setType("Prod");
bobject.setId($a.getNumber().getId());
modify($a) {
setObjectB(bobject);
};
end
This rule only executes when objectB is null, this means you won't get into
the loop as once you have created objectB the rule won't evaluate to true
again.

Yes, your rule entered in an infinite loop because when every time you
insert/modify/retract a Fact, rules are reevaluated to check if the
insertion/modification/retraction generates activations or not. In your case,
your rule is being reevaluated every time you update your $a object, the
evaluation ends firing the rule, and this starts an endless loop.
If you only have this behavior with this rule, you can consider using the
"no-loop" attribute. If your problem is multiple rules being re executed (and
you don't wont that) you can use "lock-on-active" attribute. Try to read the
documentation about these attributes for further information.
It is very important for the people new in drools to understand the life cycle
of a rule.

You can't modify bobject, becuase it doesn't exist inside the session. You
just created it a few lines above. Maybe you need an insert() or maybe you
need the bobject reference from the LHS. Something like this:
*rule* "prod"
*when*
$a :A(Type == "Prod" , objectB != "")
*then*
B bobject = *new* B();
$a.getObjectB().setType( "Prod" );
$a.getObjectB().setId($a.getNumber().getId());
*update*($a);
* end*
Note that you need to update $a and not B, because A is the inserted Fact in
your session.

Re: [rules-users] Object Referencing Error
Hi,
I tried what you said but program goes into an infinite loop.
It does not break out of the when loop only.
I did exactly as you mentioned.
In the test information I put in a.type = "Prod"
And a.bObject(new B());
Any idea whats wrong??

*update*($a);
* end*
Note that you need to update $a and not B, because A is the inserted Fact in
your session.

[rules-users] Object Referencing error:
Hi,
I am getting the following error when I try to do complex object referencing in
drools:
My class:
A{
String Type;
B objectb;
//getters and setters for above
}
My rules:
rule "prod"
when
$a :A(Type == "Prod" , objectB != "")
then
B bobject = new B();
bobject.setType( "Prod" );
bobject.setId($a.getNumber().getId());
update(bobject);
end
I want to basically output a file which has updated values of B (type, Id)

Please help! I am very new to drools! Not able to figure out why this error:
I am using eclipse and working on Windows machine. Error above was generated on
eclipse console.
Thank you.
