[flexcoders] Loaded Modules Dimensions - height="100%" doesn't work !!

[aerospc]

Hello,
  I'm adding a dynamically created module loader to a VBox.  The VBox 
has it's height set to height="100%".  The module loader has it's 
height set to "100%" with a minHeight of "400."  When loaded, the 
module loader only uses the minHeight (400).  The VBox has twice that 
much height available.  How can I have dynamically loaded modules take 
up 100% of the available space???
