Why not use the $q.when( ) to wrap angular & foreign promises:

functionfetchResults(searchText){varitems=$scope.$parent.$eval(itemExpr),term=searchText.toLowerCase(),isList=angular.isArray(items);if(isList)handleResults(items);elsehandleAsyncResults(items);functionhandleAsyncResults(items){if(!items)return;items=$q.when(items);setLoading(true);$mdUtil.nextTick(function(){items.finally(function(){setLoading(false);});},true,$scope);}}

});
} else if (items.then) {
