Master-Details with Ajax

I have in my rhtml file an master-detail data structur

  • <%= link_to_remote 'aaa', :update=>'details'... %>
  • <%= link_to_remote 'bbb', :update=>'details'... %>
  • <%= link_to_remote 'ccc', :update=>'details'... %>
  • ...

In details goes show, edit and another actions.
If I update somewhat in details I will be sure that it goes updated in
master too.

Also I put

to bottom of my updated detail

In Firefox master-item all works perfect, but IE says ‘Unknown
JavaScript Error’

Any Ideas to this problem?
