NullPointerException when using the Progress/Regress Element state toolbar command.  Take note that this only happens on the binary build.  It does not happen using the development/debug environment.

 This is fixed by changing the way the element is selected to refresh the properties view.  This is a not the ideal solution but it stabilized the properties view interface and updates it correctly
