2014.09.07 MSS Code Factory 1.11.12361 Corrected invalid exception when Viewing a null swingFocus in AttrJPanel

The AttrJPanel was checking for a null swingFocus when in View mode.  In order for the
display of sub-element objects, a null swingFocus has to be Viewable.

The population of the display widgets has also been modified such that if the AttrJPanel
is in an Unknown state, the swingFocus is ignored and no data is presented to the user.
