Cards and Lines in Drools Rules

Question

I have a Drools rule to which I send a card filled with an element, but when it is executed, I have an element. Why do I get null when this value should be "Y" for the value? When I set a breakpoint in the ACDebug.debug () method and checked the map after executing the $ map.put () function, it looks good, it has a "Y" value for the value, but after fulfilling my rules, do I have null? Does anyone have similar problems?

import java.util.Map;
import java.util.HashMap;
import edu.abc.ACDebug;

rule "POSTPROCESSOR 8"
    ruleflow-group "supress-processor"
    when
        $map:Map(keySet contains "STANDARD_ADDRESS:STREET_NAME")
    then
        ACDebug.debug($map, "Map before PUT: ");
        $map.put("/locationList/sourceAddress/fullStreet",new String("Y"));
        ACDebug.debug($map, "Map after PUT: ");
        $map.remove("STANDARD_ADDRESS:STREET_NAME");
end

Answer 1

After making changes to the map, you need to update. This allows the working memory to know that you have changed the map.

:

update( $map );
