Second subreport starts in a new page always

Problem Description

If you have 2 subreports in the summary band,  The first one starts in the middle of the page where the summary band is.  A second subreport with the exact declarations for some reason always starts in a new page.  But you want both subreports to run continuously with no blank space in between.

Solution

Be sure to set both subreports with runToBottom to false, and stretch type to NoStretch.  You can start with this working sample and add what ever else you want to change.
