[2.1] MaterialFileUploader - If a file is loaded two times, in second time the event is not call

[richelivargas]

If a file is loaded two times, in second time the event is not call. It occurs when the file is loaded by click event (hiddenFileInput). In second time the change event is not call because is the same file.

In dropzone.js

Original

return _this.hiddenFileInput.addEventListener("change", function() {
              var file, files, _i, _len;
              files = _this.hiddenFileInput.files;
              if (files.length) {
                for (_i = 0, _len = files.length; _i < _len; _i++) {
                  file = files[_i];
                  _this.addFile(file);
                }
              }
              _this.emit("addedfiles", files);
              return setupHiddenFileInput();
            });

My solution

return _this.hiddenFileInput.addEventListener("click", function() {

                _this.hiddenFileInput.value = '';

                return _this.hiddenFileInput.addEventListener("change", function() {
                    var file, files, _i, _len;
                    files = _this.hiddenFileInput.files;
                    if (files.length) {
                        for (_i = 0, _len = files.length; _i < _len; _i++) {
                            file = files[_i];
                            _this.addFile(file);
                        }
                    }
                    _this.emit("addedfiles", files);
                    return setupHiddenFileInput();

                });

            });
