TopComponent display to Output mode not working with NetBeans 8.1

Further investigation shows that if I close the windows that are “editor” mode, the window in "output" mode shows up.  If I bring even one of the windows that are in “editor” mode back up, the “output” mode window disappears again.  Normally, being able to close the windows is disabled in my code, so to do this I had to comment out the lines in the TopComponents disabling those properties.

I have created a stripped down version of my code, with only one TopComponent in “editor” mode, one in “leftSlidingSide” and one in “output” mode.  The windows don’t do much (I had to remove most of the content), but the code does show the problem I’m seeing.  I have attempted to upload this to a GitHub repository.  My first time using either Git or GitHub, so hopefully I did everything right.

Here’s the link to my GitHub repository:  https://github.com/gadamHarris/sourceCode

If you could give me any clues as to what’s going on here, I would greatly appreciate it.
