How to add additional workflow task in SharePoint workflow?

Question

I am developing a sequence workflow. It contains a Replicator and its InitialChildData property is bound to the list of strings representing users. The activity that gets replicated is the workflow task creation and the users from the list are the ones to whom the tasks are assigned to. So, I am getting multiple tasks workflow (similar to one illustrated here).

On certain workflow task update, I need to close that task and to have another one created. Since the Replicator workflow node is in charge of creating workflow tasks, how do I tell it to create an additional one? Thanks.

Answer 1

I actually solved it.

Here's the code which does the trick:

internal static void AddTask(ReplicatorActivity replicator, ReplicatorChildEventArgs args, string assignedTo)
{
  SPTaskActivity taskActivity;

  taskActivity = args.Activity as SPTaskActivity;
  replicator.CurrentChildData.Add(assignedTo);
  replicator.InitialChildData.Add(assignedTo);
}

So the idea is to modify the child data property in the replicator (which is used to generate multiple wokrflow tasks). It is necessary to add the new user to both CurrentChildData collection and the InnitialChildData collection to make it work; and that, for me, was very difficult to resolve. I am still not 100% sure why it needs to be done that way.
