[estvmachine]

Hi, i got a problem, i declare the ng-repeat of lists of objects using track by uniqueid, but the ui-select still uses '$$hashkey' like he cant reconognize the track.

<ui-select
                               multiple
                               ng-init= "typeDocumentsAll= listTypeDocs()"
                               ng-model="searchParams.typedocs"
                               theme="select2"
                               style="width: 200px;">
                      <ui-select-match placeholder="Select the type of document.">
                                {{$item.code}}
                      </ui-select-match>
                      <ui-select-choices
                            repeat="typedoc in (typeDocumentsAll | filter:$select.search) 
                                                                                  track by typedoc.code "
                      >
                        <div ng-bind="typedoc.code"></div>
                        <small>
                          name: <span ng-bind-html="''+typedoc.name | highlight: $select.search"></span>
                        </small>
                      </ui-select-choices>
                    </ui-select>

This is relationed to #665

I think this is a dupe of #665 so closing.
