I did an implementation once that depending on the runtime used a
swfupload or a dhtmlupload. It needed a servlet on the server to work
though. When you think that might be useful I can see whether I am
allowed to provide the sources.

Oh, Max, Thanks, really appreciate your answer. :-)
I'd use the http://www.w3.org/TR/FileAPI/
It's only supported by Firefox, Chrome and Opera, but caniuse.com says
Safari 6.0 will support it. I'd be willing to work on an
implementation which could be added to the platform.

I don't thnk there's an officially supported way to do this in dhtml. Webtop
uses a flash-based control even in dhtml, I believe.
I'd be happy to collaborate on a native component - the iframe method may be
the least evil... What do you think?

What is the recommended way for doing file upload with binary data in
a DHTML app? I did some research, and have some questions.
a) Is it technically possible with the current LFC without using an
iFrame?
b) Is it possible using the<form> tag?
c) Is it possible using datasets with the embedded XHR object?
d) If it's not possible, will OpenLaszlo 5.0 support that?
After looking into the source code I think that
a) it's only possible when enctype="multipart/formdata" is supported
within the LFC, see http://jira.openlaszlo.org/jira/browse/LPP-9946
b) the form tag doesn't have an "enctype" attribute like the HTML form
tag, which means you cannot set the enctype to "multipart/formdata"
c) technically yes, but LPP-9946 would have to be implemented for that
With an ugly JavaScript hack it might be possible to get it working,
using the underlying display object.
The DHTML version of Webtop supports file upload, as I saw here:
http://jira.openlaszlo.org/jira/browse/LPP-8343 How has that been
implemented? And why isn't that part of the platform? I think an RIA
platform is not complete if you cannot at least upload files with it.
For the Flash runtime, the file uploader is still in the incubator.
That means, OpenLaszlo does not have support for file upload with
components that have gone through the full QA cycle, right?
