Github user svenmeier commented on the issue: https://github.com/apache/wicket/pull/255 Yes, this is what I came up with yesterday too. We have to support file inputs in forms too, for that I changed serializeInput() to handle "file" types. I'd like to drop support for the old iframe solution in submitMultipartForm(). I'll create an issue, let's see what other devs are thinking of this.
