How to get current assigned participant id?

Question

Hi mates,
This might be a basic questions, but useful for me :)
How to get current assigned participant id from screenflow? Or How to pass it as an argument from interactive activity?
Below is what I tried.
Participant.id or Instance.participant.id - returns login user id
Thanks

Hi,
Please correct me if I understood wrong.
You want to know whether an instance is assigned or not and if assigned then you want to fetch the assigned participant id.
If this is your requirement then please find the code below and make the necessary changes into it.
Write the following code in screen flow automatic activity but before that you need to pass the instanceid as argument to the screen flow.
In the process as well as screen flow layer make an instance variable instanceid as Int.
Then make an argument variable instanceidArg as Int in both the screenflow and process layer and map accordingly so that it will take the instanceid from process layer to the screen flow layer.
Assign instanceid = id.number; in process layer automatic activity but before the global interactive activity where you have maped the screen flow.
Write the following code in screen flow automatic activity.
logMessage("============= instanceid ==============" + instanceid); //instanceid is the id of the instance that you have passed from process layer.
ProcessService ps;
InstanceFilter instF = InstanceFilter();
ps.connectTo(url : Fuego.Server.directoryURL, user : "<userid>", password : "<password>"); //In studio the userid and password will be same
logMessage("Connected");
instF.create(processService : ps);
instF.searchScope = SearchScope(participantScope : ParticipantScope.ALL, statusScope : StatusScope.ONLY_INPROCESS);
//<ProessId Name> is the id of the process where you want to know the assighed participant id
instF.addAttributeTo(variable : VarDefinition.processid, comparator : Comparison.CONTAINS, value : "/" + "<ProessId>");
instF.addAttributeTo(variable : VarDefinition.INSTANCE_NUMBER, comparator : Comparison.IS, value : Int(instanceid));
Fuego.Papi.Instance[] instances = getInstancesByFilter(ps, filter : instF);
foreach (instance in instances) {
logMessage("Assigned ?: " + instance.participantId.empty);
logMessage("instance.participantId: " + instance.participantId);
ps.disconnectFrom();
