I think I'm getting it now. The Form needs to be embedded in a panel for
the type of inclusion that I'm interested in.
I created a CnavFormPanel.java and changed CnavForm.html to
CnavFormPanel.html. I left CnavForm.java alone.
In CnavModify.java I removed this
Form form = new CnavForm("cnavFormArea");
add(form);
And added this
add(new CnavFormPanel("cnavFormArea"));
That works. Thanks for your help.
Daniel
