title: How can I make a SWF autoplay in the profile box of a facebook application?
body: <p>I want my SWF to autoplay in a Facebook profile box.  I am currently using an FBML based app but I am open to using any type that would make this easy. Using the param waitforclick=false does not work in the profile box so this is not an option.</p>
  
  <p>At first I thought this would not be possible without using an AJAX request (that is what the docs say) but after trying to do this via AJAX with no luck, I did a bit more research.  I found that in the ReverbNation facebook application "My Band", they are able to autoplay a SWF. I haven't quite figured out how they do it yet but I did take a look at the generated profile box code before clicking the SWF and after clicking the SWF.</p>

  <p>Does anyone know how to make this autoplay feature happen?  I am really having trouble finding documentation anywhere on the internet.  I am also really not sure why the generated code changes to SWFObject code after clicking.  </p>
  
  <p>Thanks!</p>
