Re: Transfering a file using DWR 3.0 disables the "input" events

Well, I think this can be considered an small "issue": Is there any way to "open" an issue in the DWR project?


From: Lance Java <lance.java@...>

DWR pollutes the file object attributes and changes it's name prior to
posting it so it clones it and swaps prior to doing a post. I guess we could
be smarter here and revert the original back to it's original state instead.


Hopefully there's a simple workaraound for your problem.
