In order for web2py to submit forms inside LOAD components via Ajax, it
must set up its own event handler to "trap" the form submission, so it can
be intercepted -- this is done here:
https://github.com/web2py/web2py/blob/master/applications/welcome/static/js/web2py.js#L307
.
If you don't want web2py to trap the form, try:
<form class="no_trap" ...>
Alternatively, create the entire form via Javascript *after* the component
has been loaded.
