How do I get FlexContentHolder content to resize?

Question

I'm creating a Flash SWC for use in an AIR project.
I created a component which I tweened from big to small.
I tried sampling the width/height at different keyframes (using both flash actions and the flex debugger) and the object always reports itself to be the original width/height.
The result is that any content I assign to the SWC container does not resize when the tween happens.
Is there another way to put dynamic flex content into a SWC?

I'll answer my own question in case anyone else runs into this.
You have to add something called FlexContentHolder to the inside of a Flex container to make this work.
  - If you add the container and set it's content you'll see nothing.
  - If you add a content holder without a container, you'll see your content, but it won't tween.
To do it right:
In Flash:
  1. Add a MovieClip
  2. Convert to Flex Container
  3. A symbol was added to the library called FlexContentHolder when you converted your movie clip
  4. Go into your newly added Flex Container and drag the FlexContentHolder from the library into your container
  5. Give the Container and ContentHolder instance names
In Flex:
  6. Add the SWC to your library
  7. Create your content group and give it an ID
  8. Create an instance of your SWC
  9. Assign your content group to the SWC's 'content' property.
10. <SWC container id>.<SWC content holder id>.content = <your content ID>
Good luck and please reply with any corrections or more efficient method you might have!
