of the java code + template from an exiting source which had
constructor code of
initWidget(uiBinder.createAndBindUi(null));
vs
initWidget(uiBinder.createAndBindUi(this));
Which works till you bind something :-)

My Java class is just the plain vanilla code when you use the wizard to
create a UIBinder object, I have not added any functionality. The only
changes I have done is to comment out the @UIField definitions that
the WindowsBuilder editor inserted. Including any one of the 6 fields
I defined results in the widget not rendering..
I am running this on GWT 2.1.1 and I also tried 2.1.0 if fails the same
in both modes.

I have a UIBinder file that specifies a HTMLPanel that contains a mix
of plain HTML and GWT widgets.
If I don't bind any of the variables, the Widget will load correctly
and display. As soon as I bind a UI field
in my code including the @UIField definition, @UiField TextBox
userid; then initializing the Widget fails in a NPE.
Thanks for any help in advance.
