With ajax=False (the default), the component is constructed on the server
at the same time as the containing page and simply inserted into the page
before it is delivered to the browser -- so there is no separate Ajax
request for the component -- it is created and rendered along with the
containing page. With ajax_trap=True, you are telling it to trap any form
submissions from within the component and send them via Ajax instead of
doing a regular post request. In that case, the original component does not
load via Ajax, but form submissions are subsequently handled via Ajax.
