To support Flash 10 (released on 9/26/2008), the Uploader required a new version of the SWFUpload Flash component (2.2.0 beta 3). This new version, still in beta, still has numerous bugs. We have worked around many of the bugs and inconsistencies in the SWFUpload code, but there are still significant compromises and issues in this release. For this reason we do not consider this version of the Uploader to be production-ready.

In the previous version of the Uploader, the Flash component worked completely "behind the scenes." To support Flash 10, the Uploader displays a Flash-based "Browse files..." button in place of a HTML button. The Flash-based button presents the following quirks:

In Firefox and IE, the Flash-based Browse button does not size correctly when the text/page is resized or zoomed.

In Firefox (FF):

  • The AIRA role for the Browse button is read correctly as "button" but the text of the button, "Browse Files", is ignored.
  • The Flash-based Browse button traps keyboard navigation, refusing to give up focus without a mouse click.

In Internet Explorer (IE):

  • ARIA is not supported by Internet Explorer.

We are exploring workarounds for most of these issues, and will have a patch out as soon as possible to fix them.

In previous versions of the Uploader the upload process would stop immediately at the moment that the Stop Upload button was clicked.vWith Infusion 1.0, we wait for the current file to complete or to error before we stop the upload process. This avoids a serious bug in the SWFUploader where the Upload process could get stuck when the Upload process as resumed.
