Flex uses an invalidation mechanism. As properties change, flags are set requesting validation of those properties at a later time. You can force validation by calling validateNow(), but it can be expensive.

If not, please explain... added to a creationComplete handler function: <code> var vBox:VBox = new VBox(); for(var i:int = 0; i < 10; i++) { var tmpBtn:Button = new Button(); tmpBtn.label = "BUTTON: " + i; vBox.addChild(tmpBtn); } this.addChild(vBox); trace('VBOX HEIGHT: ' + vBox.height); </code> OUTPUT: ------ VBOX HEIGHT: 0 <- ALWAYS ZERO No matter if I call vBox.invalidateProperties(); or any of the other invalidate functions. The buttons are added to the container fine and are displayed fine. I've also tried this with several other containers and the height is not updated after the children are added. What am I missing here?
