I was using this property to clearly distinguish the selected
header from all others. The default shading difference between a
selected and unselected item in flex is too minimal for many of our
users. Why has this item been removed and what will be replacing
it? And how can I get the coloring I am looking for now.
You can set the selectedFillColors in Flex 3 by using the
"headerStyleName" style, as seen in the following snippet.
Sorry, the docs are a bit vague on some of the replacements,
but they've been updated internally and will be fixed in the next
