How come when I create an HBox in view mode, it allows verticalGap=30 but when I create an HBox dymanically it says there is no such property movieBox.verticalGap=30; 1119: Access of possibly undefined property verticalGap through a reference with static type mx.containers:HBox.
Also, I asked this before and didn't get an answer, Why does the style explorer not have Hbox or Vbox ? http://examples.adobe.com/flex3/consulting/styleexplorer/Flex3StyleExplorer.html#
