I do not know why the change, but for a fix, you could use a labelFunction to return an empty string if the item is null.

When this code is built under Flex 2, I can select the first item in the combo's dropdown list, and selectedItem returns null, which is what I expect and want. When the code is built under Flex 3, I can't select the null item. It's shown in the list, but mousing over it doesn't highlight it, and clicking it doesn't close the dropdown. Is this a bug, or a new "feature" in Flex 3?
