angularjs - ng-repeat stuck in infinite loop angularfire 8.2 -

-

i'd figure out why ng-repeat statement runs infinite. item.members has length of 2 , contains userids = true 

<script type="text/ng-template" id="items_renderer.html">      <label>        <span class="team-description" ng-show="!item.editing">{{item.name}}</span>         <label ng-repeat="memberid in item.members">          <span>{{ getmember(memberid) }}</span>        </label>      </label> </script>    <div ui-tree="options" class="teamlist">      <ol ui-tree-nodes ng-model="teams" class="panel-teams">          <li ui-tree-node ui-tree-handle           ng-repeat="item in teams"           ng-include="'items_renderer.html'">          </li>      </ol>  </div>  $scope.getmember = (memberid) ->   memberobj = fbutil.syncobject('users/' + memberid)   memberobj.$loaded().then (ref) ->     $scope.teamuser.push ref.name     console.log $scope.teamuser     return $scope.teamuser

it keep running indefinite.

["sven woldt", "sven woldt", "sven woldt", "sven woldt", "sven woldt", "sven woldt", "sven woldt", "sven woldt", "sven woldt", "yahoo", "yahoo", "yahoo", "yahoo", "yahoo", "yahoo", "yahoo", "yahoo", "yahoo", "sven woldt", "yahoo", "sven woldt", "yahoo", "sven woldt", "yahoo",…]

so how restrict return ["sven woldt", "yahoo"]

thanks help!

it indefinite because keep pushing $scope.teamuser in $scope.getmember function. if want display name, why not try

$scope.getmember = (memberid) ->   memberobj = fbutil.syncobject('users/' + memberid)   memberobj.$loaded().then (ref) ->     return ref.name
