Hide and Show Tab in TabNavigator in Flex

I have the following TabNavigator setup:

It will not work if you simply set the “visible” attribute to hide a certain tab like this:

    this.tab3.visible = false;

The correct way to do this is:

    tabNavigator.getTabAt(2).visible = false;

    // This will remove the tab completely from the layout - not taking spaces
    tabNavigator.getTabAt(2).includeInLayout = false;

Not sure the exact reason, but it works for me.
