Of course not. What I am saying is that client side validation is pretty
much useless since you have to perform it again server side anyway (so
what's the point?). Since you have to check the data again on the server
and since you have no guarantee that Javascript is even enabled, placing
your "intelligence" on the client side is a bad idea. IMHO warnings and
such should be generated by the server with Javascript used at most maybe
to provide some extra details.
I guess the main thing I wanted to impart was to not make the mistake of
relying on client side validation (a common problem).

Can you imaging how frustrating it is when your site is completely unusable
because you do not have Javascript enabled (or your browser does not
support the exact flavour that the site was designed with)?
If an extra submit makes your site that boring I think you have bigger
problems to deal with.

In the real world you cannot trust the end user to send you "safe"
data. If your application depends on a specific tree of events you better
make sure that you are not just trusting your Javascript to create those
dependencies. This is not an argument about user rights at all and if you
want to cast it as such, most Javascript seems to be intended to reduce
user freedom (pop up windows, removal of browser buttons, enforcing
specific browser versions, etc.).
All IMHO of course.
