I have a problem. In Flex Mobile project, I can not use the usual mx:TabNavigator. I need to dynamically create tabs and close them. With s:TabbedViewNavigator I can not dynamically create "Views", and tabs for them. I could not close these tabs. what can I do to use tabNavigator? Thanks.

P.S. I use FlashBuilder 4.5 with AIR 2.6 S开发者_Go百科DK

Mobile Flex project support only a very limited amount of the old mx components, the TabNavigator is not one of them.

For a dynamic tab navigation use a for example a ButtonBar linked with a ViewNavigator.
