Drools 4.0 problem: insert (drl) not reflected StatefulSession.
by Michael Waluk
I just upgraded to Drools 4.0 and changed my assertObject calls to insert.
I also switched from WorkingMemory to StatefulSession. The rules seem to be
fine, but I am not able to retrieve any inserted objects from the working
memory for some reason. Here is what I'm doing. I'd appreciate any
suggestions...
StatefulSession *workingMemory* = getActiveWorkingMemories(id);
*workingMemory*.fireAllRules();
// Here is the rule that fires:
*
rule* "RecognizeBenefitsProgramEvent" *
** when* $edit: BenefitsProgramModelEdit()
* then*
* insert* (*new* *BenefitsProgramEvent*("BenefitsProgramEvent",
$edit.getValidFrom(), "AnnualEnrollmentEvent")); *
** System*.out.println("Rule RecognizeBenefitsProgramEvent fired "); *
**end*
I see the print statement in the console but the inserted object is not
actually in the working memory. I look using this:
Iterator events = *workingMemory*.iterateObjects(new ClassObjectFilter(
BenefitsProgramEvent.class));
This iterator is empty. I also debug and look at the assetMap inside
workingMemory and it never changes.
Thanks,
Michael

Cryptic error message: org.drools.compiler.FunctionError@191394e
by Scott Reed
I have converted my 3.1 DRL to 4.0, think I have the dependencies worked out (removed
antlr-30ea8.jar) and now I am getting a cryptic error message from the DRL compiler:
Rules.getRuleBase. org.drools.compiler.FunctionError@191394e
org.drools.rule.InvalidRulePackage: org.drools.compiler.FunctionError@191394e
at org.drools.rule.Package.checkValidity(Package.java:412)
at org.drools.common.AbstractRuleBase.addPackage(AbstractRuleBase.java:292)
...
Am I missing something with the plugin, is my DRL so badly munged the compiler can't explain what's
wrong, or what?
Thanks,
Scott

4.0 Dependencies
by Scott Reed
1) Please tell me where I can find the definitive list of dependencies for the 4.0 release.
The manual lists them but also says to look for README_DEPENDENCIES.txt in the lib dir but I do not
see it.
I am getting the following error:
Exception in thread "main" java.lang.NoSuchMethodError:
org.antlr.runtime.DFA.unpackEncodedString(Ljava/lang/String;)[S
at org.drools.lang.DRLParser.<clinit>(DRLParser.java:7223)
at org.drools.compiler.DrlParser.getParser(DrlParser.java:204)
at org.drools.compiler.DrlParser.parse(DrlParser.java:60)
at org.drools.compiler.PackageBuilder.addPackageFromDrl(PackageBuilder.java:158)
My classpath has antlr-3.0ea8.jar.
2) What am I missing?

Eclispe Auto-Complete Problem
by dpark
Is it only me, but when I use the Eclipse plugin and when I auto-complete I
get every permutation of what I've specified in my dsl.
For example:
In dsl I've registered the following:
[condition]There is no calculated fact called "{name}"=not
CalculatedFact(name == "{name}")
In drl when I auto-complete in a condition, I get the following
possibilities:
* There
* There is
* There is no
* There is no calculated
* There is no calculated fact
* There is no calculated fact called
* There is no calculated fact called "{name}"
Ideally, all i want to show up is the last statement. Is there any way to
filter out all of the ones above it?
Dave

Function Call in LHS
by Rafael Alcemar
Hello guys! This is my first question for the list. I've defined a function
in my DRL file to evaluate if a user can do a specific operation in my
system. This function returns a boolean result. My question is if I can use
this function in the test of LHS.
For example:
rule "Cliente pode alugar"
when
eval(teste)
then
System.out.println("XXXXXX");
end
function boolean teste( ) {
return true;
}
Please, if anybody has some help, send me.
Thanks!
