The problem appears to be that the rule being generated is just flat wrong. I'm starting to think this is a bug in decision tables for 4.0 GA.

 

The following entry:

 

 

ACTION

anAnswer: BooleanAnswer

anAnswer.setAnswer($param);

Allowed

TRUE

TRUE

 

 

Generates this rule:

 

rule "postponePart_10"

     

      when

            PoolInfo(courtLocation == "101", statusCode >= 0, statusCode <= 2, numberFta < 1, numberOfDeferralsPosted < 2, daysBeforeSummons>= 1, daysBeforeSummons<= 1)

      then

            anAnswer: BooleanAnswer.anAnswer.setAnswer(true);;

end

 

This doesn't seem right at all. What I'm trying to do is to call the setAnswer method on the object I passed in with:

 

            StatelessSession session = participantRuleBase.newStatelessSession();

           

            //now create some test data

            PoolInfo pool = part.getActivePool();

            BooleanAnswer answer = new BooleanAnswer();

           

            Object[] rules = new Object[]{pool, answer};

            session.execute(rules);

           

            return answer.isTrue();

 

 

Advice?

 

Thanks.

I'm having trouble figuring out the ACTION section of a decision table. Everything else appears to be working.

 

My rules result in a simple True/False condition. To do this in a decision table, I've created a class called BooleanAnswer that looks like:

 

public class BooleanAnswer {

           

            private boolean   answer;

           

           

            /**

             * no-arg constructor

             */

            public BooleanAnswer(){

            }

           

 

            /**

             * create your own default answer

             * @param answer the answer to set

             */

            public BooleanAnswer(boolean answer){

                        setAnswer(answer);

            }

           

 

            /**

             * @return the answer

             */

            public boolean isTrue() {

                        return answer;

            }

           

 

            /**

             * @param answer the answer to set

             */

            public void setAnswer(boolean answer) {

                        this.answer = answer;

            }

}

 

 

Then I create a decision table with the following ACTION in it:

 

ACTION

 

answer: BooleanAnswer

 

answer.setAnswer($param);

 

Allowed

 

TRUE

 

 

 

 

 

 

This generates the following errors:

Help for a newbie, please?
