In previous versions, after setting a new renderer, the selectbox would be automatically redrawn, applying the new renderer.

Since 7.0.4 (maybe from 6.5.7, but I am not sure), the selectboxes do not apply the change immediately. I have tried using selectbox.invalidate() right after setting the new renderer, but it does not help.

I have created a fiddle and a post in the forum:

Thanks!
