[rules-users] FW: Decision Tables

[Hehl, Thomas]

I am still stuck with this problem. Anyone with decision table experience
care to lend a hand, please?

 

The docs for decision tables seem to lack a great deal. I'd be happy to work
on them some, but gotta get this one working.

 

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:
