Flex beta 2 - ComboBox not working

Question

it seems like ComboBoxes are not working with sdk 4.0.0.10485; while they were with 4.0.0.7219
i simply click and nothing happens..
code is this:
    <mx:ComboBox>
        <mx:ArrayCollection>
            <fx:String>AK</fx:String>
            <fx:String>AL</fx:String>
            <fx:String>AR</fx:String>
        </mx:ArrayCollection>       
    </mx:ComboBox>
but also using other kind of dataProviders it's the same..
am i mistaken?
Thanks!

Answer 1

ok, round 10,
this last round triggered my memory about a caching issue in lists that was resolved about 2 months ago its starting to smell a little like that so I need to do a search in jira and see if it is the same thing. In the mean time this is using the spark component, see if it gets closer to what you are chasing.
(it only works for item 1 and item 2 - i'm lazy )
