script: 

    $.each(data, function(i, v) {         $scope.numbers.push(v.orderraderid);          if ($.inarray($.trim(v.orderraderid), $scope.numbers) == -1)             $scope.numbers.push(v.orderraderid);              if ($.inarray($.trim(v.objektbeteckning), $scope.objektdescriptions) == -1)                 $scope.objektdescriptions.push(v.objektbeteckning);              if ($.inarray(v.kundnamn, $scope.customernames) == -1)                 $scope.customernames.push(v.kundnamn);              if ($.inarray(v.anmdatum, $scope.registerdates) == -1)                  $scope.registerdates.push(v.anmdatum);              if ($.inarray($.trim(v.status), $scope.advstatuses) == -1)                 $scope.advstatuses.push(v.status);              if ($.inarray($.trim(v.utforare), $scope.managers) == -1)                 $scope.managers.push(v.utforare);     });

all lists except last 1 renders "status" first option selected default.

ive tried hardcoding the select attribute "selected=selected" did not work. ive tried setting via script so: 

$(".advancedsearch select option").each(function () {                    $(this).removeattr('selected');                });

but nothing works. doing wrong?

took me while changed 

 <option  ng:repeat="status in advstatuses" value="{{status}}">{{status}}</option>

to

 <option  ng:repeat="status in advstatuses" value="">{{status}}</option>

and solved problem. don't understand why happened , appreciate explenation if has one?
