Perhaps I am completely misunderstanding, but when I add multiple files to the UploadPanel via the add button, they all show up as a list, then when I click the Upload button each file's spinner starts and when I look at Firebug and my server, I see mutiple connections at the same time.
The way I have been testing this is with large files 10+ mb so I know it takes more then a couple seconds to upload.
I have tried the singleUpload: true, and singleUpload: false.
My understanding is that singleUpload: true is that only one file gets posted per form submit and singleUpload: false is all the files in the queue get submited in a single form submit.
Just to be clear, I am curious about having this:
1. FileOne.xml -> begins upload, when finished, whether failed or success, go to next.
2. FileTwo.xml -> then as each file gets upload each spinner starts, and shows success or error icon.
3. FileThree.xml ..
4. FileFour.xml ..
5. FileFive.xml -> until the last file gets uploaded.
singleUpload: false <-- perfect, however I want to make the requests dependent on the request ahead of it. So lets say an option of "simultaneousTransfers: 2", two will upload at the same time, when one finishes the next starts, or if it was set to 1, then only one will upload, once a finished status is returned, the next starts.
