    FileUpload doDecode Exception

    Gern Raudn Newbie

      hi there!

       

      i got the following problem everytime i try to upload a file using the rich:fileupload:

       

      Caused by: java.lang.NullPointerException
              at org.richfaces.renderkit.FileUploadRendererBase.doDecode(FileUploadRen
      dererBase.java:139)
              at org.ajax4jsf.renderkit.RendererBase.decode(RendererBase.java:75)
              at javax.faces.component.UIComponentBase.decode(UIComponentBase.java:579
      )
              ... 68 more
      

       

      i found a few things on google about it, but none of the solutions worked. filters are in correct order, web.xml includes the maxrequestsize and createtempfile-definitions but nothing helped.

       

      i'm using richfaces 3.3.3 final and myfaces on jboss

       

      thanks in advance

          Hi,

            Maybe you should show more, page code or config lines.

            the code i used is completely identical with the one on http://livedemo.exadel.com/richfaces-demo/richfaces/fileUpload.jsf, i didn't change anything

             

            my web.xml is about 600 lines long now, don't know if it's worth posting

            at least i could post filters and -mapping:

              Hi,

                Remove ADF Faces Filter and have a try.

                nope, didn't make a difference.

                  RF filter should be first in chain. And according to spec - filters which mappings uses url mapping - registered first even if defined below the filter which mapping uses servlet name. So all the filters which you defined - came before RF one.

                    okay understood. but what could i possibly do? i think those urlmappings have to be there (not all of the code is written by me), so i need some workaround or something... is there a way to make this work?

                      thanks for trying to help me, but i really can't see many differences. i tried to handle the request like the example's javafile, changed the order of my web.xml-content and such things, i don't get it.

                       

                      the error starts with

                       

                      ERROR [BaseXMLFilter] Exception in the filter chain

                        I have the same problem and it's not the matter of wrong myfaces filter order - I even don't use myfaces. The stack trace looks like this:

                        java.lang.NullPointerException
                                at org.richfaces.renderkit.FileUploadRendererBase.doDecode(FileUploadRendererBase.java:139)

                                ...
                        

                        It occurs only in IE9. It works when I switch to IE8 mode in developer tools (F12), but adding:

                        <meta content="IE=8" http-equiv="X-UA-Compatible" />

                        like suggested on a french developers forum doesn't help.

                         

                        I use RichFaces 3.3.3.Final.

                         

                        I will appreciate any reply

                          This is also causing me problem

                          Jboss 5.0.1

                          RichFaces 3.3.3.Final

                          Only seems to be on IE 9

                           

                          Adding the IE header did fix it, but looking for a better solution.  THis previously worked, so something else we did started causing this, and we did not adjust anything in web.xml.


                          if($ofjq.browser.msie){
                            
                          if(parseInt($ofjq.browser.version,10) > 8) {
                            

                          if(window.location.href.indexOf('docupload.seam') > -1 ){
                            


                          $ofjq('head').append('<meta content="IE=8" http-equiv="X-UA-Compatible" />');
                            

                          }
                            
                          }

                              }

                            Hi,

                             

                            We seam to have the same problem in our applications. Is there a solution already without putting all IE browsers in IE8 mode? Maybe a quick(and dirty) fix? You don't want that in terms of performance of javascript...

                              Try adding the encType to the form:

                               

                              <a4j:form ignoreDupResponses="true" enctype="multipart/form-data" >

                                The problem is in MyFaces Extensions Filter can't be used simultaneously with RichFace Filter

                                Myfaces filter will overwrite the Richface  multiDataForm data
