    Custom fileUpload renderer

    Leo K Newbie

      Hi

       

      I would like to know if it´s feasible to change the fileUpload component renderer, just like other JSF components.

       

      I just can´t find what´s is... that thing below ;-)

       

      <render-kit>
           <renderer>
               <component-family>org.richfaces.component.FileUpload</component-family>
               <renderer-type>org.richfaces.renderkit.html.FileUploadRenderer</renderer-type>
               <renderer-class>?</renderer-class>
           </renderer>
      </render-kit>

       

      Yeah. It´s not there at the Table 6.178.

       

      I just want to change two things

       

      [1] add an hyperlink to the uploaded file, so the user can just download it as well (maybe I can do this in the renderer)

      [2] change the initial list of "loaded" files to those ones present in a specific directory.

       

      Looks like something easy to do, but I must confess I am quite lost, specially on identifying where to look first.

       

      So any help is welcome

       

      Best regards

          Forgot to say, RF 3.3.3.

            Well, half of the problem seems to be solved.

             

            To change filenames to links, here´s what I had to do

             

            [1] it seems the renderer is

             

            <render-kit>

                 <renderer>

                     <component-family>org.richfaces.component.FileUpload</component-family>

                     <renderer-type>org.richfaces.renderkit.html.FileUploadRenderer</renderer-type>

                     <renderer-class>org.richfaces.renderkit.html.FileUploadRenderer</renderer-class>

                 </renderer>

            </render-kit>

             

            [2] to get FileUploadRenderer, I had to decompile the class from the jar using jad, since this file seems to be absent of the richfaces source code (I don´t know why exactly, maybe it´s there with another name)

             

            [3] then, in this file, I´ve changed the js file name to something I can change (see bold part)

             

            private final InternetResource scripts[] = {

                    new PrototypeScript(), new AjaxScript(),getResource("/org/richfaces/renderkit/html/scripts/utils.js"), getResource("/org/richfaces/renderkit/html/scripts/json/json-dom.js"), getResource("/org/richfaces/renderkit/html/js/FileUpload2.js"), getResource("/org/richfaces/renderkit/html/js/swfobject.js"), getResource("/org/richfaces/renderkit/html/js/progressBar.js"), getResource("/org/ajax4jsf/javascript/scripts/form.js")

                };

             

            [4] finally, in the js file above, I´ve found FileUploadEntry.template

             

            [newET(function (context) { return Richfaces.evalMacro("fileName",context)})]


            and I´ve replaced it to

             

            [new E('a',{'style':'','onclick': function (context) { return'alert(1);return false;';},      'className':function (context) { return 'rich-fileupload-anc' + Richfaces.evalMacro("labelClassName", context) +Richfaces.evalMacro("className", context); },'href':'#'},

            [new ET(function (context) { returnRichfaces.evalMacro("fileName", context)})])]),

             

            so now, the filename comes inside an anchor that has a javascript action on it (alert), so all I have to do is to put some javascript up there.

             

            so, the other half of my problem seems to be how to get the initial list of uploaded files populated :-)

             

            best regards
