Got that. How do I code the action so it
calls the setAnswer() method on my BooleanAnswer object?

This isn't bug, you aren't using drools correctly.
Only valid java can be used in an Action. anAnswer:BooleanAnswer is not valid
java and shows up in your generated code:
anAnswer:
BooleanAnswer.anAnswer.setAnswer(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.

Subject: Decision Tables
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 |
|
|
|
|
|
|
|
|
|
|
|
