How to assign Activity to Participant with less assigned Instances??

Question

Hi!
I'm trying to automatically assign the next Interactive Activity to the participant who has less assigned instances.
I already know how to get a list of the participants who have the corresponding role, but I don't know how to get the number of assigned instances of a determined process that each participant has.
Any ideas?? Thanks in advance!

OK, I finally managed to do it :^O
I get all participants with the Role "Iniciador", then get how many instances of the process they have assigned. And finally I send this instance to the participant with less work.
logMessage("AutoAssign - Entering...");
DirectorySession dirSession = DirectorySession.currentEngineSession;
DirOrganizationalRole role = DirOrganizationalRole.fetch(session : dirSession, id : "Iniciador");
Fuego.Fdi.DirHumanParticipant[] participants = role.fetchAssignedParticipants();
BusinessProcess.connectTo(url : Fuego.Server.directoryURL, user : "redscare", password : "redscare", process : activity.process.name);
String nombre="";
int c=0;
logMessage("AutoAssign - Entering foreach");
foreach (element in participants) {
     filtro = InstanceFilter();
     filtro.create(processService : BusinessProcess.processService);
     filtro.searchScope = SearchScope(participantScope : ParticipantScope.ALL, statusScope : StatusScope.ONLY_INPROCESS);
     filtro.addAttributeTo(variable : VarDefinition.PARTICIPANT_ID, comparator : Comparison.IS, value : element.id);
     instances = BusinessProcess.getInstancesByFilter(filter : filtro);
     if(nombre=="" || instances.length()<c){
          nombre=element.id;
          c=instances.length();
logMessage("AutoAssign - Exiting foreach");
participant.next = Participant.find(name : nombre);
participant.sticky = true;
logMessage("AutoAssign - Exit. Participant.next= "+participant.next.name);
