[Solved] Upload only first time

[Tetha]

Hi,
I have an Upload control. This is the code;

  @(Html.Telerik().Upload()
  .Name("UploadImages")
  .Multiple(false)
  .ClientEvents(events => events
          .OnSuccess("onUploadImagesSuccess")
                  )
  .Async(async => async
          .Save("SalvaImmaginePrincipale", "Immobile")
          .AutoUpload(true)
   )
   .ShowFileList(false)
)
The problem is that only the first upload works, when I try to upload a second file the browse window
doesn't appear and I can not upload files.

Thanks in advance.
Mirko
