Grouping features out from an Array, please help!

Hello,

I have in hand an identifyResults Array. I want to extract all its features only to a new array "zoomFeatures" but failed.

Here are the part of the codes and error message extracted.
Hope someone could help!

Thanks in advance

private var zoomFeatures:Array;
private function identifyResultFunction(identifyResults:Array, clickGraphic:Graphic = null):void
{
if (identifyResults && identifyResults.length > 0)
{
          zoomFeatures.splice(0,zoomFeatures.length);
              for (var k:Number = 0 ; k < identifyResults.length ; k++)
              {
               var kResult:IdentifyResult = new IdentifyResult;
               kResult = identifyResults;
               zoomFeatures.push(kResult.feature);
                          }
             }
}

TypeError: Error #1009: ????????? Null ???????????????????????????

Did you ever set the zoomFeature array to a new Array? Either

private var zoomFeatures:Array = new Array;

or

zoomFeatures = new Array();
