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?
