I develop a FB app using Flash using wmode=”direct” (for 3D graphics).
In Internet Explorer, every time I popup any FB dialog (e.g Purchase Credits dialog), the flash disappears and when the dialog is closed, the flash does not re-appear…
I tried to set the visibility after dialog is closed:
http://developers.facebook.com/docs/appsonfacebook/tutorial/ (under “Special Considerations for Adobe Flash developers”), but it didn’t work.
I’ve also tried the use FB.Init hideFlashCallback:
http://developers.facebook.com/blog/post/555/ (under “Detecting visibility of Flash objects in Canvas apps”), but it doesn’t seem to call the callback function…
Any one had the same issue and manage to make it work?
Any other suggestions?
P.S – I use swfobject to embed the SWF file.
Thank a lot!

UPDATE: I removed the appId param from the FB JS url:
<script type="text/javascript" src="http://connect.facebook.net/en_US/all.js#appId=XXXX&xfbml=1"></script>
and now the hideFlashCallback is executed, but still – the flash does not re-appear…
I’ve updated the section Special Considerations for Adobe Flash developers because the code snippet was a bit out-of-date.
The new snippet should give you an idea of how to use the hideFlashCallback, whose semantics have changed since that now out-of-date blog post, in that the function now takes a flash element as an argument. (Unfortunately, we haven’t redocumented it yet, but will soon). One thing to note is that the callback does not currently work on IE8, but will after a fix gets pushed next Tuesday.
That said, it should work without that callback. It may be caused by a javascript fatal that stops script execution before the re-showing happens. Look in your javascript console to see if you see any errors.
Otherwise, if you can give me the canvas URL for your application, I can look into it.
