-               
-               for ( i; i < childrenArray.length; i++ )
-               {
-                   if ( child == childrenArray[ i ])
-                   {
-                       childrenArray.splice( i, 1 );
-                        delete childrenIdDict[child.id];

-                   }

+                var childIndex:int = getChildIndex(child);
+                
+                if (childIndex >= 0) {
+                    childrenArray.splice(childIndex, 1);
+                }
