Thanks again John.
I was able to piece together snippets from your example and
that made our sample work for crud update finally.
It correctly validates the empty field and displays the error message.
The 3 fixes I made were
1. The hidden fields at the bottom helped, I believe:
<input value="{{=form.formkey}}" type="hidden" name="_formkey" />
<input value="{{=form.formname}}" type="hidden" name="_formname" /
>
2.
<form action=="{{=request.env.path_info}}" <-- I was missing that
code in the ""
3.
in the Controller, the key important logic for the case of a crud
update was
elif session.action == "update":
id=request.args[0]
response.view="%s/%s/%s.html" %
(request.controller,request.function, request.args[0])
return dict(form=crud.update(db.testtable,id))
