Maybe I should not rely on the DataGrid doing the sorting and instead take the bother to sort the underlying data? As I understand the documentation that should automatically sort the DataGrid. Or maybe I should try set up a really simple example that exposes my problem and then maybe someone can see what I am doing wrong? Flex has really got me hooked!
