incomplete audit?
by H.C.
I have started capturing audit info for my ruleflow execution and I see
multiple audit files being generated (audit.log, audit1.log and audit2.log).
While each file has content, only audit.log seems to display anything in the
audit view. However, I see the audit info in the viewer seems to end sooner
than my actual execution goes. I can hit breakpoints in later ruleflow
groups than are recorded in the audit. Is that captured in the other files
and if so, how can I load those into the audit view?

Rules categorization/packages
by Amit Kumar
Hello All,
I am looking to organize the rules in different categories. But for
distribution purposes We are creating packages for different
roles/processing phases
So a rule will reside in one pckage but for navigation it can belong to
multiple categories
So packages are like Shirts, Pants, Shoes, Sweaters
Categories are Color, Material, Size, Gender and those have sub categories
witin them
We have rules which will device the category of the item
Like "red rule", "blue rule", "cloth rule", leather rule"
Now the problem we are facing is for category rules is if I define the rule
in Shirt package .. then I will not be able ot use it in Pant package.. Will
have to redefine it.
The other problem in this scenario is If I have a price rule in Shirt
package and the category is "Blue Color" and "XL Size" then I will have to
put it in both categories
When I put the "Blue Rule" on "Blue Category" and "XL Rule" on "XL
Category" and I put the rule in both categories.. will it be an "and"
relationship or will be an "OR"
Regards,
Amit

Question About Programmatically Creating Drools Rules Remotely
by S. McKee
Hello,
I am running a Drools Guvnor server. While it is not an issue to create
rules through the UI, I do have a need to create rules and packages
through a Java program that I am coding that will connect remotely to
the Guvnor server from another box. Does anyone know if this is this
possible? If so, could I get pointed in the right direction for making
this happen?
Thank You,
Scott McKee

Re: [rules-users] rules-users Digest, Vol 40, Issue 55
by Nilima R
Hi All,
Can someone tell me how to use create enums with Dynamic values in Guvnor.
For example I need enum which does not contain static value like A,B,C
rather these A,B,C values come from database.

I think I need to clarify a few things. First the OOME is not in running
the
rules but on marshalling the state for the flow, which I do after each
command using a custom CommandService that marshals the session after each
command is executed. Second, the ValidationRuleFlowGroup is only going to
insert a ValidationResult() if there is something that is invalid. So a
valid set of facts would have no ValidationResult() in memory, hence
wanting
to split to a "valid" branch on "not ValidationResult()".

Thanks,
I tried this but I don't see my ruleflow group rules coming back and
re-processing once the high priority auto focus rules in my new
"maintenance" agenda group have executed. Do my rules in my ruleflow group
now also need an agenda group and auto-focus set to be re-evaluated?

OutOfMemoryError with non-existence check in flow XOR split
by heldeen
I am using drools marshalling for persistence and am getting an OOME with my
simple rule flow. I have a custom CommandService that persists at the end of
each execution. (I am not using JPA :-( ).
In the rule flow I have a split that checks for the non-existence of a
simple pojo using "not ValidationResult()" as one of the constraints. The
other constraint is ValidationResult(valid == false). I get an
OutOfMemoryError using the "not" in one of the constraints. Changing "not
ValidationResult()" to "ValidationResult(valid == true)" results in normal
operation.
The flow is essentially Start->ValidationRuleFlowGroup->XOR Split->Valid
Action XOR Invalid Action -> End. The ValidationRuleFlowGroup has a simple
set of rules that will insert a ValidationResult() fact if something is not
valid.
Anyone have any idea why checking for the non-existence of a fact causes
this error. I'll post the pojo and the stack trace below.
public class ValidationResult {
private boolean isValid;
private String message;
public boolean isValid() {
return isValid;
}
public void setValid(boolean isValid) {
this.isValid = isValid;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
