The problem here is that dropdownlist use a popupAnchor to display options. The click is therefor now "owned" by the callout and thus callout is being closed.
The callout function should include this possibility and this could be considered a sdk bug as having options in a callout is highly probable and this behavior is not desired. If you happens to have a scoll bar in the dropdown list as well a drag of it will also close the callout making selection impossible -- View this message in context: http://apache-flex-users.2333346.n4.nabble.com/DropDownList-in-a-Callout-Button-closes-the-Callout-after-selecting-an-item-in-the-DropDownList-tp4204p5231.html Sent from the Apache Flex Users mailing list archive at Nabble.com.
