About upload a 0 size .txt file with ie7 or ie8

[marsxmu]

In my web project,I can upload .txt file larger than 0 successfully,however  when I'm attempting to upload a 0 size .txt file,I get the message  "Transfer error occurred" on the brower,it seems that there is nothing upload. I have tried to debug the error,all the listener like onuploadcomplete,ontyperejected and fileUploadListener were not triggered.And It works good on firefox brower.

The codes are  as following:

<rich:fileUpload fileUploadListener="#{fileUploadBean.listener}"
                       maxFilesQuantity="1"
                       id="uploadFile"
                       required="true"
                       allowFlash="auto"
                       acceptedTypes="txt,csv,xls,xlsx"
                       listWidth="344px" listHeight="40px" immediateUpload="true"
                       addControlLabel="Browse..."
                       disabled="#{empty createList.listName}">

              <a4j:support event="onuploadcomplete" immediate="true" reRender="info,textEmptyWarn,updateStatusBottom,updateStatusTop" actionListener="#{createList.setSuccessUpload}" />
              <a4j:support event="ontyperejected" immediate="true" actionListener="#{fileUploadBean.setFailureUpload}" />

            </rich:fileUpload>

Can anyone give me an idea?

Hi,

Thank you for reporting the problem! I've created https://jira.jboss.org/browse/RF-8891 for this. The problem seems to be affecting only Flash-enabled mode of rich:fileUpload, so you can try switching it off.

Thank you for your reply,however I can't turn off  the Flash mode since it will object my product request.

It's a hack but you can try to redefine fileupload js function and insert verification.

something like this:

var backup_flashAdd = FileUpload.prototype._flashAdd;
FileUpload.prototype._flashAdd = function (files) {
     // delete files from array with size==0
     // see original code below
     // call original function
    backup_flashAdd.call(this, files);
}

or like this (original code + verification + comments):

Object.extend(FileUpload.prototype, {
     _flashAdd: function(files) {
     if (this.disabled) return;
     var filesArray = [];
     for (var i=this.entries.length; i<files.length;i++)
     {
          var file = files[i];
          if (file.size!=0) {// file size verification here
               this.currentInput.value = files[i].name;
               this.createFrame();
               var newEntry = new FileUploadEntry(this.currentInput, this, file.size, file.type, file.creator, file.creationDate, file.modificationDate);
               this.entries.push(newEntry);
               filesArray.push(newEntry);
               if (this.runUpload) {
                    newEntry.setState(FileUploadEntry.READY);
               } else {
                    newEntry.setState(FileUploadEntry.INITIALIZED);
               }
               var newUpload = this.currentInput.cloneNode(true);
               this.currentInput.style.cssText = "position: absolute; right: 0px; top: 0px; display: none; visibility: hidden;";
               newUpload.id = this.id + ":file" + (this.idCounter++);
               newUpload.value = '';
               this.currentInput.parentNode.appendChild(newUpload);
               this.currentInput = newUpload;
          } else { // end size verification
          // put some alert here if needed
          }
     }
     if (this.events.onadd) {
          this.element.fire("rich:onadd", { entries : filesArray });
     }
     if (this.runUpload) {
          this.upload();
     }
     }
});

Currently we are not planning 3.x releases. Please use workaround posted by Pavel.
