>From the front end, multi file uploads must be done using JS to create additional file input elements on the fly. Uploading them "via AJAX" is all about perception, as you can't actually do it since the JS would need to stream the bytes of the selected files (which is of course not allowed). The pure HTML/JS way to implement this is by having an iframe that actually points to another page with the form. Using JS, you can submit that form and emit notifications to the containing page when the page in the frame reloads. Throw in a little CSS and you end up with what looks and feels like an AJAX file upload (this is exactly how gmail's smooth upload works).
The tricky part unfortunately is dealing with T5. I don't know how you can create new components on the fly. It's not as easy as just creating a new element in pure JS, since the containing T5 form will need to know about that component and how to bind a value to it. Input on this subject is sorely needed. chris Lance Java wrote: > The html file object only supports 1 file at a time, it's also locked down > by browser security so you can't set the value via javascript. > To upload multiple files you can either use multiple file objects with some > user friendly javascript or use an applet or a flash component. > > I've seen some open source multi-upload applets floating about... have never > used one though. > Facebook for example uses an applet to upload multiple photos > > 2008/8/28 Massimo Lusetti <[EMAIL PROTECTED]> > > >> On Thu, Aug 28, 2008 at 5:08 PM, ProAdmin Dariusz Dwornikowski >> <[EMAIL PROTECTED]> wrote: >> >> >>> I think some major ajax has to be used. >>> >> Look into Component Reference on Tapestry5 documentation site >> >> >> -- >> Massimo >> http://meridio.blogspot.com >> >> --------------------------------------------------------------------- >> To unsubscribe, e-mail: [EMAIL PROTECTED] >> For additional commands, e-mail: [EMAIL PROTECTED] >> >> >> > > -- http://thegodcode.net
