Using FFJ 2.0 build 1160.  Upon selecting multiple JLabels in the Component
Selector ( ctrl clicking ), clicking on the "..." next to foreground color
under Properties and setting User Code: null under the Form Connection tab only
changes the first component selected.  The error "Exception in
org.netbeans.modules.form.FormPropertyEditor Property Editor." appears in an
model Exception error popup window several times whenever one of the previously
mentioned JLables are selected in the Component Inspector.  It is impossible to
get the "Property Editor: foreground (Color)" window to open by clicking
the "..." in foreground after that.  The only way around it is to select a
color in the drop down, such as lightGray.  This removes the buggy netbeans
error, and you can proceed to set the foreground to null individually for each
JLabel.

This problem exists for every component that I've tried, I'm just using JLables
as an example.  It only happens when you select User code: and type something
in the text area.  If you select a swatch or set an RGB color the problem does
not present itself.
