Note that there is a known issue that will prevent this sample from working correctly in the APL authoring tool (Display button in the Build tab). Echo Show/Spot, Fire TV, and Fire tablet devices are not impacted by this issue. In the authoring tool, a SetPage command with position=relative and value=1 on the final page of a Pager with navigation=wrap makes the Pager goes to the second to last page instead of wrapping around to page 1.
