Problem was in Datagrid's Skin where whole caretIndicator component was commented out, cause its not needed. If it is uncommented, and set caretIndicatorFill's alpha to 0, now Datagrid key nav works properly!
Probably somewhere in SDK, when tabbing; caretIndicator existence is ignored, but if you click on Datagrid and try key nav, it does not work without caretIndicator component defined in Datagrid's Skin. -- View this message in context: http://apache-flex-users.2333346.n4.nabble.com/Keyboard-navigation-in-Spark-Datagrid-from-SDK-4-15-does-not-work-until-TAB-ed-somewhere-tp14480p14657.html Sent from the Apache Flex Users mailing list archive at Nabble.com.
