RichFaces 3 is no longer supported.  Migrate your application to RichFaces 4 for support with modern browsers.

Consider...

Object.extend(FileUpload.prototype, {

            add: function (A) {

                if (this.disabled) {

                    return

                }

                if (!A.value) {

                    return

                }

                if (!this.checkFileType(A.value) || !this.checkDuplicated(A)) {

                    var F = A.value;

                    var B = A.cloneNode(true);

                    B.value = "";

                    A.parentNode.replaceChild(B, A);

                    this.currentInput = B;

                    if (this.events.ontyperejected) {

                        this.element.fire("rich:ontyperejected", {

                            fileName: F

                        })

                    }

                    return

                }

                var D = new FileUploadEntry(A, this);

                this.entries.push(D);

                if (this.runUpload) {

                    D.setState(FileUploadEntry.READY)

                } else {

                    D.setState(FileUploadEntry.INITIALIZED)

                }

                // When the object was being cloned, it's onchange value was being fired as well.

                // was

                // var B = A.cloneNode(true);

                // A.onchange = null;

                // begin

                var onchangeAttribute = $j(A).attr('onchange');

                $j(A).attr('onchange', '');

                var B = A.cloneNode(false);

                $j(B).attr(onchange, onchangeAttribute);

                // done

                A.style.cssText = "position: absolute; right: 0px; top: 0px; display: none; visibility: hidden;";

                B.id = this.id + ":file" + (this.idCounter++);

                B.value = "";

                this.currentInput = B;

                A.parentNode.appendChild(B);

                if (this.events.onadd) {

                    var C = [];

                    C.push(D);

                    this.element.fire("rich:onadd", {

                        entries: C

                    })

                }

                if (this.runUpload) {

                    this.upload()

                }

            }

        });

Try to add attribute noDuplicate="true". It works for me.

This worked great for me. Thanks!

Code as used in 3.3.4:

var onchangeAttribute = $(elt).attr('onchange');

$(elt).attr('onchange', '');

var newUpload = elt.cloneNode(false);

$(newUpload).attr('onchange', onchangeAttribute);

I just tried noDuplicate="true". Works just as well.

I'll probably go with this route as it's less invasive.

Thanks Andrey

It's a problem with the version 36 of Chrome, with the version 37 it's work again.

Chrome related issues:

http://code.google.com/p/chromium/issues/detail?id=71536

http://code.google.com/p/chromium/issues/detail?id=388795

Works for me as well. Thanks Andrey!

Ha! I saw your comment about noDuplicate after I had already gotten a new UI jar compiled with the JS fix, and my first thought was that it was only a variation on the JS change (and I don't think I've really found noDuplicate documented, still), so I just stuck with that until I ran into another problem related to this. But ultimately it is noDuplicate that fixes (or at least works around) this for me, and yes, it is a much better path than mucking about with local changes to richfaces-ui jar!

I just wanted to say thank you, Andrey, and others in this thread -- this is very helpful for bridging the time to a Chrome fix.

Now, back to that 3.x to 4.x migration I happened to be working on already. :-)
