hi folks, when the fileupload in a multipart form fails, other form fields that are part of the form submission are reset (not preserved). the cause of this "misbehavior" is, that under certain scenarios (file too big, invalid content type, ...), the MultipartServletWebRequest can't be created and thus the form field values can not be read from the HttpServletRequest. creating a normal WebRequest won't work, as the request parameters are encoded into the multipart part of the request.
a possible (nasty) workaround (for eg. file size too big) could be something like this: + try to create a MSWR with the desired maxSize + in case of failure, create a new MSWR with Bytes.MAX + parse the request, read & store the request parameters, read&discard uploaded files + mark the MSWR "invalid" so that users can't call getFile() (or whatever it's called) the problem with this approach is, that somebody can possibly upload a Long.MAX_VALUE byte sized file and thus really compromise the server. this could be limited with an application setting "fallbackMaxSize", which can be set by the user and is used instead of Bytes.MAX. i guess we have to decide whether we want to support this, or just leave it as it's now. https://issues.apache.org/jira/browse/WICKET-406 wdyt?
