Hi, am bit confused about 4.0.0MR2. It is a official release i assume. But the name(milestone) seems it is a Beeta release. is it really a beeta version?If so when will be the standard edition planned to release? Thanks and Regs, Basha

Hello,
I downloaded the JBoss Rules 4.0 Eclipse IDE. I built a small
project with about 120 rules. My test asserts around 500 objects.
When I try to add one more rule (regardless of the content of the
rule) I get the error below, stating no such method error. Even if I
add the following rule, I still get the error:
rule "new rule"
when
Object()
then
System.out.print("test");
end
What other problems can throw these errors?
Thanks,
Steven

I guess one of the Attributes in IndividualNok has no getter / setter
method.
Just verify

Hi,
The following problem encountered:
I have a rule defintion :
----------------------------------------------dpd.drl
package ruletest;
import ruletest.IndividualNok;
rule Female_NOK_sex_401
//when (IndividualNok(nokRelationship==401) ||
IndividualNok(nokRelationship==402))
when (IndividualNok(nokRelationship==401) ||
IndividualNok(nokRelationship==402) ||
IndividualNok(nokRelationship==403))
then
System.out.println("abc");
end
------------------------------------------------
When I tried the commented out LSH, it works, however, when i add one
more expression to it , it fails with the following exceptions:
Exception in thread "main" java.lang.NullPointerException

org.drools.base.extractors.BaseObjectClassFieldExtractor.getLongValue(Ba

Any idea about this? is it a bug
When I tried to create an additional rule with the 2 expression, it
still fails. This error can be reproduced with the followng code:
-------------------------the Main Class's main method
public static void main(String[] args) {
// TODO code application logic here
final PackageBuilder builder = new PackageBuilder();
try {
builder.addPackageFromDrl( new InputStreamReader(
Main.class.getResourceAsStream( "dpd.drl" ) ) );
} catch (DroolsParserException ex) {
ex.printStackTrace();
} catch (IOException ex) {
ex.printStackTrace();
}
final RuleBase ruleBase = RuleBaseFactory.newRuleBase();
try {
ruleBase.addPackage( builder.getPackage() );
} catch (Exception ex) {
ex.printStackTrace();
}
final StatefulSession session = ruleBase.newStatefulSession();
IndividualNok individualNok = new IndividualNok();
session.assertObject(individualNok);
session.fireAllRules();
session.dispose();
}
