I wrote already a bug report about this issue, but no one responded.
For an application I need to disable and enable tabs on the fly. So I built a TabBar with a ViewStack as a dataProvider and NavigatorContent as the single items. Then I tried disabling a NavigatorContent component so that the tab is disabled. But it is still enabled and can be selected. How can I disable a single tab? Do I have to create a custom solution or wait until the TabNavigator component is ported to Spark? (Maybe I should fall back to the halo component)
Also the enabled property of the TabBar doesn't disable the tab content. So there seems to be no connection between the data and the TabBar.
