> I'm trying to submit a nested form via ajax to upload a file  inside modal window.
> I get an exception:
> java.lang.IllegalStateException: ServletRequest does not contain multipart content. One possible solution is to explicitly call Form.setMultipart(true), Wicket tries its best to auto-detect multipart forms but there are certain situation where it cannot.
> at org.apache.wicket.protocol.http.servlet.MultipartServletWebRequest.<init>(MultipartServletWebRequest.java:113) 
> After debug:
> FileUploadBase.isMultipartContent get false because
> if (contentType.toLowerCase().startsWith(MULTIPART))   - contentType = application/x-www-form-urlencoded 
> It only occurs on IE browser (both IE7 and IE8).
