facebook javascript SDK: FB.Canvas.setAutoResize iFrame not working?

Question

we built a facebook application with ruby/rails and facebooker (iframe application) and are currently stuck with the FB.Canvas.setAutoResize which seems to fail in some cases. u

Answer 1

Some key things to make sure are set in the application settings:

1. Canvas Settings -> Render Method = iFrame
   
2. Canvas Settings -> iFrame Size = Resizable
   
3. Migrations -> new SDK = Enabled

Next adjust your code by adding a timeout (250 seems to work best, but you may want to experiment futther). I've tested this in FF3.6 and IE7+. In IE there is a momentary flash of the vertical scrollbar which I'm still trying to fix.
