I have a panel with a TabNavigator with two tabs (VBoxes).
Each VBox contains a DataGrid. I update the dataprovider of both
DataGrids using an Array for each in ActionScript, but only the
DataGrid of the selected tab (default index 0) gets updated, and
the second tab's DataGrid throws an error (TypeError: Error #1009:
Cannot access a property or method of a null object reference) and
doesn't update. Any help would be much appreciated. Code
