I’m using observe\_form for a simple ajax rating/voting system. When the  
user changes the form it works great. However, I replace the form with a  
:partial in my ajax data returned to reflect the new rating. For some  
reason after one successful operation it does not work again… changing  
the form has no effect.

If I view the page source it all looks as it should.

Does observe\_form stop working once you replace the observed form?

Er, sorry for the reply to myself, but I found a bug in trac describing  
my exact problem. Apparently it is a prototype bug dealing with radio  
buttons. ☹

I need to search Rails Trac before posting here!
