Also, to chime in, there are in fact sometimes timing problems (in various browser/embedding environments) with accessing a SWF (even in the ONLOAD event handler) and trying to access it's ExternalInterface functions. There are a few "recent" threads about that topic.
I have a helper library called CheckPlayer (http://checkplayer.flensed.com/) which implements a set of logic to "wait and check for" EI availability, and then when it's definitively ready, it calls a function of your choice (your "callback") to let your code know. So, either using that library, or implementing your own logic similar to that, is the key... you have to "asynchronously" wait for the EI to become ready (after the call to embedSWF) before you are able to make calls to it (especially if embedSWF is called during loading of the page before dom is ready!). --Kyle -------------------------------------------------- From: "Aran Rhee" <aran.r...@gmail.com> Sent: Friday, January 30, 2009 3:31 AM To: <swfobject@googlegroups.com> Subject: RE: Trying to access the flash element right after swfobject.embedSWF results in error > > Embedding / ID - so when the swf gets written to the page, it will > overwrite > the old div etc and take over the ID.
