[xwiki-users] no acces to POST data via $request.getName

I would like to grep some data from a file upload, but can't find a way to do it. Here are a simple example {{velocity}} #foreach($prop in $request.getParameterNames()) request.$prop #end {{html}} <form action="" enctype="multipart/form-data" method="post"> <div> <fieldset> <legend>Attach files to this document</legend> <div> <input name="a" value="" size="40" type="text"> <input name="b" value="" size="40" type="file"> <input name="c" value="" size="40" type="text"> </div> <div> <input value="Attach" class="button" type="submit"> <input value="Cancel" class="button" type="reset"> </div> </fieldset> </div> </form> {{/html}} {{/velocity}} It returns request.a request.c What happened to 'b', is et a bug or a feature? Are there any way to access the value of 'b'? I've been looking at the java code but haven't found anything claiming it should be gone. -Rune
