I've run into an interesting situation with Flex: I've got a Java servlet that will generate a Zip file when the user clicks a button in Flex. But the file download dialog after the server action requires the user to click a button. It throws this error:
Error: Error #2176: Certain actions, such as those that display a pop-up window, may only be invoked upon user interaction, for example by a mouse click or button press. So how do you handle these situations? After the server responds successfully, do you display a second button to do the actual Flex file download? - Alex
