I am developing a SharePoint sequence workflow. It is consisted of the main part and a sequence activity which I have implemented separately. I have used that sequence activity for one of the workflow nodes. This is the approach described by Scott Hiller.
Basically, my workflow reads a list item and based on that it creates a bunch of workflow tasks. Let's assume that my workflow creates 5 tasks. I need to make my workflow mark the rest of the tasks to Complete once the first 3 tasks are completed by the user. I do not know how to get to the rest of the tasks in the sequence activity, i.e. I do not know how to reference them. I tried creating a property in the sequence activity which would store the workflow item, but it generates an error (I believe only simple types, DateTime and strings are allowed).
