    Datagrid sorting issues with 1/0 items to consider

      Hi all,


      I have an issue I can't find a way to fix. I am using a datagrid which I pouplate through a XMListCollection based on some XML datas.




      var prefs:XML = <files>
      <file name="@toto" favourite="1"/>
      <file name="@toto"favourite="0"/>




      var xlc:XMLListCollection = new XMLListCollection( new XMLList ( prefs.file) );




      <mx:DataGrid id="filesList" width="100%" height="100%" dataProvider="{xlc}">
      <mx:DataGridColumn width="25" dataField="@favourite"sortCompareFunction="favourite_sortCompareFunc"/>


      Sorting fucnction:


      private function favourite_sortCompareFunc(itemA:Object, itemB:Object):int {
          var value1:Number = Number( itemA.@favourite );
          var value2:Number = Number( itemB.@favourite );
          if(value1 < value2){
               var n:Number = -1;
               return n;
          else if(value1 > value2){
               return 1;
               return 0;
          return 1;


      Once loaded, the datagrid appears in a "normal state":

      But if I try to sort first column, it becomes messy

      I think it might be related to the fact that the data to be sorted is only made of 0 & 1. But I can't imagine this kind of situations is not fixable.

      Any hint ?


      Thanks in advance for any advice,
