Did you have any luck with the (ugly) workaround I suggested? -----Original Message----- From: Murray, Christopher [mailto:[EMAIL PROTECTED]] Sent: Tuesday, November 19, 2002 21:41 To: 'Struts Users Mailing List' Subject: RE: Loosing my parameter in the multipart request
It would also appear that the request parameters are only revealed once the ActionForm has been populated. i.e. my reset method exploded but when I commented it out the validate worked fine. -----Original Message----- From: Kris Schneider [mailto:[EMAIL PROTECTED]] Sent: 19 November 2002 13:39 To: Struts Users Mailing List Subject: Re: Loosing my parameter in the multipart request If the request content type isn't application/x-www-form-urlencoded, then the getParameter family of methods won't work. However, I'm guessing that Struts will handle this for you if you make userAction a property on an ActionForm. Your app logic may need to change in that case since Struts will populate the form *after* reset has been called. In other words, you'd do something like this in your Action: UploadForm upload = (UploadForm)form; if (Constants.STAGE_ACTION_METHOD.equals(upload.getUserAction())) { ... } Quoting "Murray, Christopher" <[EMAIL PROTECTED]>: > Hey there guys n gals, > > I seem to be loosing a parameter of my request when I submit a multi-part > form. > > In the page I have a, > > <input type="hidden" name="userAction"/> > > this is written to by a call to, > > <a > href="javascript:submitFormDispatch('UploadForm','performUpload')">LINK</a> > > which calls, > > function submitFormDispatch( formname, value ) > { > var form = document.forms[ formname ]; > var elements = form.elements; > > elements[ 'userAction' ].value = value; > alert("userAction =" + value); > form.submit(); > } > > Now I know this is working because the alert pops up to tell me. > > When the reset method is called in the ActionForm I get a null pointer > exception because no parameter is found for the action mapping set in the > struts-config.xml, > > <action path="/.../upload" > type="com...UploadAction" > name="UploadForm" > scope="session" > validate="true" > input="/.../upload.jsp" > parameter="userAction"> > <forward name="displayInputForm" > path="/.../upload.jsp"></forward> > <forward name="confirmUpload" > path="/.../Upload_confirmed.jsp"></forward> > <forward name="fail" path="/.../error"/> > </action> > > And then in the form I've been using, > > public void reset(ActionMapping mapping, HttpServletRequest request){ > > FWLog log = FWLogManager.getLog("UploadActionForm"); > log.debug("Entering UploadActionForm.reset"); > > System.out.println("mapping.getParameter() = " + > mapping.getParameter()); > System.out.println("request.getParameter(mapping.getParameter()) = > "); > System.out.println(request.getParameter(mapping.getParameter())); > > System.out.println("request = " + request.toString()); > > if > (request.getParameter(mapping.getParameter()).equals(Constants.STAGE_ACTION_ > METHOD)){ > > this.emailText = null; > contactId = null; > log.debug("email text has been reset."); > } > > log.debug("Entering UploadActionForm.reset"); > } > > When all this executes this outputs > > mapping.getParameter() = userAction > request.getParameter(mapping.getParameter()) = > null > request = org.apache.struts.upload.MultipartRequestWrapper@799ca4 > > java.lang.NullPointerException > at com...web.action.UploadActionForm.reset(Unknown Source) > > Guessing that a Multipart request is a different request object. > > Have you got any suggestions ? > > Is this possible ? > > -- > To unsubscribe, e-mail: > <mailto:[EMAIL PROTECTED]> > For additional commands, e-mail: > <mailto:[EMAIL PROTECTED]> > -- Kris Schneider <mailto:[EMAIL PROTECTED]> D.O.Tech <http://www.dotech.com/> -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]> -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]> -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
