rich:fileUpload How to avoid transfer error when uploading empty file (0 bytes)

vital3 Jan 21, 2010 4:37 AM

<rich:fileUpload id="uploadFileId"

        fileUploadListener="#{listener}"
    allowFlash="false"
    maxFilesQuantity="1"
    immediateUpload="true" />

I use such rich:fileUpload on page and have no problem to upload any non-empty file. But it fails when i try to upload any zero-byte file. Uploading doesn't end or I get transfer error (it depends on browser). onupload event was fired but listener wasn't called. I use richfaces 3.3.2.GA. The same behavior I saw on richfaces demo site.

Can somebody advise me what to do to avoid such behaviour (how to handle empty file uploads proper way in other words)?

checked under FF 3.5 with RF 3.3.3 SNAPSHOT

with allowFlash="false" - works for me fine
with allowFlash=true - do not works. But the problem seems in flash plugin itself which didn't allow to send 0b files.

Thanks for advice. I downloaded the latest snapshot of RF 3.3.3. This helped only partially in my case. For now I have no problem with empty file uploading when I browse the page in IE7. But no difference in behaviour when I browse the page in Firefox 3.5.7 (or in Firefox 3.0 - just doesn't matter) - onuploadcomplete event not fired.
What additional information should I provide to clarify the case?

Thanks, everything is ok. It works even with RF 3.3.3 BETA1 (I've just disabled FF addons. But I still get transfer error with RF 3.3.2.GA Is there any workaround for RF 3.3.2.GA? /I have to avoid the use of BETA in current project that uses RF/)
