I see same behavior even on the RichFaces live demo (using IE7):
Downloading picture ... lasts forever. Attaching screenshot:
Does anyone know the reason?
I have the same problem. IE also endlessly waits for the download to finish, spinning the icon, keeping the hourglass.
I tried partial refresh of the Upload and/or the enclosing form.
Also tried h:form and a4j:form with various settings.
The only way to get rid of it is to reload the whole page by browser refresh or standard form submit.
I refuse to do a regular form submit! It's too nasty with IE complaining incessantly about reposting form data.
However, if I use a4j:support event="onuploadcomplete" reRender="result,upload" to refresh the FileUpload component the add file will re-enable.
Then the stuck behavior only happens the first time.
I suspect some hidden field needs to be read and it has no value until after the first upload.
