The label's not the problem, it's selecting the item when it's null. I found
that it works if I replace null with an empty string in the dataProvider, and
guard against type errors in the code that reads selectedItem.

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.

Subject: [SPAM] [flexcoders] Can't
select null item in ComboBox
I have
some code that was originally written under Flex 2, where a ComboBox's data
provider is an array of objects, with the first element set to 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?
