Web Player SendMessage Array Parameters

I'm using the SendMessage function in my html page to send arrays to the unity web player. No matter how I initialize and use the array it always comes through as a length 1024 array in the player, whether I pass in one shorter or longer. Is this a bug? And if not how do I fix this issue?

 function SendObjectListToUnity()
 {
     //var objects=new Array();
     //var objects=new Array(3);
     var objects =[];
     /*objects[0]="object1";
     objects[1]="object2";
     objects[2]="object3";*/
     for (var i=0;i<1100;i++)
         objects[i]=i;
     u.getUnity().SendMessage("Global Scripts", "SetObjectList", objects);
 }

 public void SetObjectList(object[] objects)
 {
     Log(objects.Length);
 }
