HTML Component in flex

Question

Hey all, I'm using Drumbeat HTMLComponent in flex. So I have multiple iframes on stage that all add to the history. So what I've been trying to do is catch their complete event and then use js to remove an entry from the history.

My problem is I can't catch the htmlCreationComplete event.

this.addEventListener("htmlCreationComplete", onAdCreated);
HTMLManager.onHTMLCreationComplete(adFrame.id);
adFrame.source=url to ad;

I've tried getting an instance of HTMLManager and adding the listener to that, but it didn't work. Any suggestions would be great.

Thanks
