问题
I have a strange problem where I am trying to build tabs in a tab navigator with a combination of mxml and AS-3. Somehow the last mxml tab contents are visible even on chosing the AS tabs- the problem is resolved afer the mxml tab-2 is viewed once
e.g. when you have tab 2 as the chosen option and then click the button on top, the AS created tabs also show the mxml-tab contents- goes away after the tab is clicked through.
Any ideas what's happened- and how to handle this?
