Subject Re: OT, ajax form submission
Date Thu, 27 Sep 2007 22:14:09 GMT
The first thing I noticed was that your onclick
handler  attribute doesn't "return false;" after
executing your Ajax method; perhaps it's doing both
the Ajax submit and a regular one (easily verifiable)?

It might be less traumatic to just figure out what's
wrong with the built-in Ajax, though :/
