It is still not clear for us what is the new issue in the current case.
There are two Upload widgets - one synchronous and one asynchronous - which one is causing the problem? Is the request not send to the Action or it is sent successfully, but the files are not there?
In order to best describe the problem, I would suggest you to send us an isolated project
, which demonstrates it. This way we will be able to debug it and inspect it locally, which will lead to faster resolving.
