Help creating Proxy Plugin for an Ad SWC

Question

I'm trying to create a plugin for an ad component, where ad video playback is all handled in a SWC.
I took the OSMSPlayer example, and modifed the constructor to load my plugin using the players factory object, and once loaded, I continue with the player setup and configuration.  There doesn't seem to be a problem here, everything loads fine.
I then proceeded to create a proxy plugin.
Within ProxyElement, when set proxyElement is called, I create a SerialElement, and add the passed mediaElement as the first child of the SerialElement.
I then add a loadTrait to the proxyElement, and listen for the LoadEvent.LOAD_STATE_CHANGE event.  When this is fired, I insert a MediaElement (preroll), which has a PlayTrait, DisplayTrait, TimeTrait and AudioTrait, as the first child of the proxied serialElement, and call play.  The preroll video plays fine, i hear audio and see the time updates in the player, but the video is not visible.  If I then pause the video, it suddenly appears, and is visible for the remainder of the clip.  Once the preroll is complete, the orginal mediaElement plays fine.
I followed the MASTPlugin example, as I am trying to do something similar, except my video playback is handled via a SWC (added to the DisplayTrait).  If I just insert a plain VideoElement as the preroll and load a flv it plays fine, so its something specific to my MediaElement impl, but I can't figure out why it doesn't display until I hit pause.
Any help would be greatly appreciated, I've already burned hours trying to figure this out.
Also, looking at the use case chart below, I probably actually need to create a reference plugin.  Does anyone have an example of a reference plugin?

The behavior you're describing sounds like a bug -- if you can post a small, self-contained example that reproduces the problem, that would be
very helpful.
You might also want to look at DurationElement and SWFElement.  When you wrap the latter in the former, you can display a SWF but augment it with the ability to play, pause, have a duration, and seek.  The ExamplePlayer sample app has at least one example showing how to use this (I think it's called "Timed Image" and uses ImageElement rather than SWFElement, but the approach is the same).
As for reference plugins, the ControlBarPluginSample (+ ControlBarPlugin) is a good example of a reference plugin.  This sample shows how you can load and display the player chrome dynamically from a plugin.
