First of all Im new to Flex so please be patient with me 
So im using FlashDevelop and im trying to build an user interface. Im trying to do it using VBox and HBox components but i guess im missing something because everytime i add a component (TextField or Label) to a Box ti reports an error on build (cannot convert flash.text::TextField@ee7c161 to mx.core.IUIComponent.).
What am i missing here? Any other advice?
