Window Event, problem with attaching listener

Question

Can someone point me in the right direction here
1:
window.nativeWindow.addEventListener(air.Event.RESIZE,onResizeComplete);
2:
window.nativeWindow.addEventListener(air.Event.MOVE,onMoveComplete);
Line #1 works perfect, line #2 throws an error: "TypeError:
Error #2007: Parameter type must be non-null."
Both functions
onResizeComplete and
onMoveComplete are defined the same way.

Answer 1

try deferring the remove until other events have been processed, like this: SwingUtilities.invokeLater(new Runnable() {
  public void run() {
    jTabbedPane1.removeTabAt(1);
});
