Progress bar not visible in GAE, when deployed

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use a servlet for GAE like FilesApiUploadAction
2. Deploy to Google App Engine 
3. Upload a file using client-side MultiUploader 

What is the expected output? What do you see instead?
I'm expecting to see a progress bar while the file is uploaded. 
Instead, I see the progress bar starting at the end of the upload 

What version of the product are you using? On what operating system?
0.6.4-SNAPSHOT

Please provide any additional information below.
The strange behaviour is that I get this message:
gwtupload.server.UploadLogger$JavaLogger info: MemoryUploadListener  created 
new instance. (slow=0, requestSize=621116)
.. after this one:
gwtupload.server.UploadLogger$JavaLogger info: Received new file, stored in 
blobstore with the key ..

.. so it seems the Listener starts after having finished the upload!

This issue is related with the impossibility of tracking the progress in GAE 
infrastructure, although in dev mode it is possible.

See issue#106

Is this issue resolved somehow? The issue 106 which this is duplicate of was 
fixed in a way that doesn't affect this issue.
If there is still no way to make progressbar work on GAE, it might be useful to 
mention it in the description of the library. I just deployed my fancy 
progressbar only to find out it's not working and then I found this issue ;)
