Dynamically embedded swf, has it ever worked

Question

I have to repost it. Wondering what adobe will say about it.
I have tried this for a couple of days. I created a swf object in window.onload (also tried to create it directly while the script was loaded ), then call an AS function from JS. statically embedded swf works for both IE8 and FF, FF also fine for dynamically loading. In IE, this call externalinterface.call("echo", "as returns " + b); always shows "as returns false". The callback function has never worked in other approches with dynamic creation. Anyone has good experience?
Thanks.
