Hi,
Sorry haven't been on the list for a while, busy with a project, which keeps me now
really busy.
We have here an exception which does not seem to make any sense and we're a bit lost
in the why and where this happens.
Any help will be appreciated.
Thanks,
Darko IVANCAN
----------------------------------
Steps to reproduce:
1. Log in to jBRMS
2. Created Package as “com.xyz.abcservice.rules”
3. Imported two jars (“rulescore.jar”,” sampleDomain.jar”) into Model.
4. Created New Rule with the following content
package com.xyz.abcservice.rules;
import domain.Accommodation1;
import java.util.List;
import com.xyz.common.rules.api.GenericRuleViolation;
global java.util.List errList;
rule "Conflict Rule 1"
when
accommodation1:Accommodation1(name == "Car")
accommodation2:Accommodation1(name == "Caravan")
then
errList.add(new
GenericRuleViolation(accommodation1,"Invalid cabin combination."));
end
4. Validate it…
------------Output------------------
