Wrapping a Task Flow as a Region
You can drag to your page a bounded task flow that includes page fragments and create it as a region on the page. The default activity of the task flow appears in the editor and in the page when it is first run.
At run time, you can use page navigation (described in the lesson titled “Implementing Navigation on Pages”) to navigate through the task flow. As you do this, the region refreshes without redrawing the entire page (partial page refresh).
