Flex action wait for network response

I have sma开发者_JAVA百科ll Flex web based util with single button. On this button click a request is sent to server and the response must be read in the same call. This is important not to wait for response with event handler (which is trivial).

Basically this is synchronous call.

I am ok with blocking ui and so on.

Is it possible to implement?

thank you

You haven't any way to get result of the server call synchronously in Flash Player.
