multi-part request params

If I'm uploading an attachment, and putting extra params into the request, xwiki doesn't seem to be allowing me to access them. I noticed that the request is a struts MultiPartRequestWrapper, but it doesn't seem to contain any of the parameters at runtime. e.g set a breakpoint in XWikiAction.execute and you'll notice that the request does not have the "filename" parameter, and in fact to access that param, the UploadAction has to manually parse it. Shouldn't the form params be in the request? Anyone know why this is happening and how to fix it (newer ver of struts maybe?) I think this struts bug may be related: http://issues.apache.org/ bugzilla/show_bug.cgi?id=17583 Matt
