External Routing Service

Question

has anyone implemented an external routing service for the human task activity? I find the documentation lacking in that direction. I need to be able to define the assignee as a user or group at runtime. Apparently you can't do that in 10.1.3.1 without an external routing service

Answer 1

I think that what you need is writing a external routing policy. That is also what I am trying to do. Here is the only doc I have found on the subject :

I think we both want to make the same thing : make the human tasks more dynamic. ANd according to me, the external routing policy is the best (or less bad) solution.
As in the example below
What I still don't manage to do is creating a Participant that is "Parallel "or "Management Chain".
This work fine in the onOutcomeUpdated() method :
ObjectFactory objFactory = new ObjectFactory();
Participants participants = objFactory.createParticipants();
Participant participant = objFactory.createParticipantsTypeParticipant();
participant.setName("Loan Agent");
ResourceType resource2 = objFactory.createResourceType(user);
resource2.setIsGroup(false);
resource2.setType("STATIC");
participant.getResource().add(resource2);
But this doesn't work :
ObjectFactory objFactory = new ObjectFactory();
Participants participants = objFactory.createParticipants();
Parallel participant = objFactory.createParticipantsTypeParallel();
participant.setName("Loan Agent");
ResourceType resource2 = objFactory.createResourceType(user);
resource2.setIsGroup(false);
resource2.setType("STATIC");
participant.getResource().add(resource2);
Does anyone have an idea of how to make this bit of code work? Or any other idea about how to make a human task dynamically change its behaviour (for example switching from sequential pattern to parallel pattern according to a user action) is welcome!
