I am attempting to pass information from a task created within a workflow to its corresponding task form. Prior to the CreateTask activity, I create an SPWorkflowTaskProperties and fill it with the usual info (title, assigned-to, etc). I also add some elements to the ExtendedProperties property. However, those custom properties never make it into the Task.

I’ve tried setting the property key to:

  • the Guid of one of my task’ content type’s fields;
  • the internal name of one of my task’ content type’s fields;
  • an unrelated name (in the hopes of getting the info into the task’s properties instead of its fields).

Nothing works. The task, once created, contains only the built-in field values I have set. None of values I explicitly added to the extended properties show up.

The (simplified) sequence of my activities is as follows:

  • PrepareTask. This is a custom activity that contains the SPWorkflowTaskProperties
  • CreateTask. The task properties are bound to the one in the PrepareTask activity.
  • OnTaskCreated. The task properties are bound to the one in the PrepareTask activity.
  • While (task not complete)
    • OnTaskChanged

I am using WSS 3.0 SP1 and an ASPX (NOT InfoPath) task form.

  1. I still don’t know why my original solution didn’t work. But I have found a workaround. My sequence of activities is now:

    • CreateTask
    • OnTaskCreated
    • CopyTaskItems. This is a custom activity that puts values into my custom task’s fields, then updates the task.
    • While (task not complete)
      • OnTaskChanged

    So I have to create the task, then immediately poke values into it and update.

    I hope this will help some future reader of this question.
