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.
