Whereas Flex 3 included built-in support for deferred content creation in all of the Halo containers, Flex 4 only offers this feature with the SkinnableContainer Spark container. With the DeferredContentGroup, you can utilize deferred instantiation in the lighter-weight Spark Group container.
I created this, primarily, because I needed it for the new Spark ViewStack navigator that I’m currently working on (which I’ll be wrapping up and releasing soon), but I saw no reason to not release this as a standalone component.
I didn’t feel like I needed to post a demo or directions on how to use this. If you know how to use a Group and you know how to use the creationPolicy attribute, then you know how to use this component (although I do have a demo checked into the source code repository).
