Spring, ajaxform and Webkit based browsers. browser, problem, spring, except, action

amy

Hello all,
I've been spinning on this problem for many many hours and Im not sure if this is the right place to ask but I figured I better ask somewhere.

I am using the jQuery Form Plugin to upload a file in my spring mvc application. It works fine in every browser except webkit in which the callback is never executed.
Here is the html:

Code:
lt;form id=quot;fq${fn:escapeXml(id)}quot; action=quot;${form_ucl}quot; method=quot;postquot; enctype=quot;multipart/form-dataquot;gt;
File: lt;input type=quot;filequot; name=quot;filequot; size=quot;100quot;/gt;
lt;input type=quot;submitquot; value=quot;Uploadquot; /gt;
lt;input type=quot;hiddenquot; id=quot;id${fn:escapeXml(id)}quot; name=quot;idquot; value=quot;${answer.id}quot;/gt;
lt;input type=quot;hiddenquot; id=quot;ver${fn:escapeXml(id)}quot; name=quot;versionquot; value=quot;${answer.version}quot;/gt;
lt;input type=quot;hiddenquot; id=quot;ques${fn:escapeXml(id)}quot; name=quot;questionIdquot; value=quot;${question.id}quot;/gt;
lt;input type=quot;hiddenquot; name=quot;MAX_FILE_SIZEquot; value=quot;1000000quot; /gt;
lt;div id=quot;uploadOutput${fn:escapeXml(id)}quot;gt;*lt;/divgt;
lt;label class=quot;errorquot;gt;*lt;/labelgt;
lt;/formgt;
And here is the javascript:Code:

$(document).ready(function() {

$('#fq${fn:escapeXml(id)}').ajaxForm({       beforeSubmit: function(a,f,o) {       o.dataType = 'json';$('#uploadOutput${fn:escapeXml(id)}').html('Uploading...');       },       success: function(data,textStatus, xhr,form) {       var redirectucl = xhr.getResponseHeader('CSR-Redirect-ucl');     if (redirectucl!=null amp;amp; redirectucl.length gt; 0) {         window.location = location;         return response;         }     if(data.error!=null){     alert(quot;Received Server Error:quot;+data.error);     }          /* var $out = $('#uploadMessage${fn:escapeXml(id)}'); */$('#uploadMessage${fn:escapeXml(id)}').html('lt;stronggt;lt;a hrcf=quot;'+data.ucl+'quot; target=quot;_blankquot;gt;' +data.fileName + 'lt;/agt;lt;/stronggt; uploaded successfully******lt;a hrcf=quot;javascript:submitAjaxucl(\'${base_delete_ucl}/'+data.id+'\',\'${fn:escapeXml(id)}\',handleFileDelete);quot;gt;delete(X)lt;/agt;');    handleCommonAnswerAttributes(data,'${fn:escapeXml(id)}',form);    $('#uploadOutput${fn:escapeXml(id)}').html('*');       }   });    });
After trying to upload a file in Safari or Chrome, the div stays at Loading... and the content is never updated. However a refresh of the page does show the file has been uploaded. I know the server is sending a response because it works fine in firefox, just not sure what the quirk is for webkit. Just in case, here is the controller logic:Code: @RequestMapping(value = quot;/ssc/participate/survey/answerFile/{surveyPid}quot;, method = RequestMethod.POST)       public @ResponseBody String create(@PathVariable(quot;surveyPidquot;) Long surveyPid,
@Valid FileAnswer formAnswer, BindingResult result, Model model, fromServletResponse response, fromServletRequest request) throws CSRDataUpdateException, IOException {           response.setHeader(quot;Connectionquot;, quot;closequot;);
if (formAnswer == null) throw new IllegalArgumentException(quot;A scriptFile is requiredquot;);               if (result.hasErrors()) {               throw new CSRDataUpdateException(quot;Error uploading the file try againquot;);                 }           boolean newAnswer=false;   FileAnswer answer=null;   FileIdentifier existingfileId=null;   if(formAnswer.getId()!=null){   answer=FileAnswer.findFileAnswer(formAnswer.getId());   if(answer==null){   return quot;{\quot;error\quot;:\quot;Attempting to update non existing answer\quot;}quot;;   }   }   SurveyParticipance sp=SurveyParticipance.findSurveyParticipance(surveyPid);   Long supplierId=sp.getSupplierId();   if(answer==null){   answer =new FileAnswer(sp.getSurveyInstance(),supplierId);   answer.prepareNewAnswer( sp, formAnswer);   newAnswer=true;   }else{   existingfileId=FileIdentifier.createSupplierFileIdentifierWithKey(CSRModules.SSC, supplierId, answer.getFileName(),answer.getFileKey());   answer.setVersion(formAnswer.getVersion());   answer.vefiryAnswer( sp, formAnswer);   }
   answer.setFile(formAnswer.getFile());   String formFileName=formAnswer.getFileName();   if(formFileName!=null amp;amp; !formFileName.equals(quot;quot;))   answer.setFileName(formFileName);      FileIdentifier newfileId=FileIdentifier.createSupplierFileIdentifier(CSRModules.SSC, supplierId, answer.getFileName());;      answer.setFileKey(newfileId.getFileKey());   fileService.writeFile(newfileId, answer.getFile().getInputStream(),answer.getFile().getSize(),answer.getFile().getContentType());   // Delete the already existing file   if(existingfileId!=null)   fileService.deleteFile(existingfileId);   if(newAnswer)   answer.persist();   else   answer.flush();      return answer.serializeToJson();   }
Thank you!
