So I've seen Jiras for this topic, but I'm not quite sure how to reassign a swimlane instance to new actors. Here's the situation:

Swimlane instance is assigned to actors: "A" & "B"

String actorsString = "A,B";
String[] actorsArray = actorsString.split(",");
swimlaneInstance.setPooledActors(actorsArray);

Swimlane instance is assigned to actors: "C" & "D"

String actorsString = "C,D";
String[] actorsArray = actorsString.split(",");
swimlaneInstance.setPooledActors(actorsArray);

This, however, just adds C & D (i.e. the swimlane now is assigned to "A", "B", "C", and "D") versus replacing A & B. How do I get this to reassign the swimlane instance to C & D? Thanks!
