Using a hidden field does not work as you are not in a form. That is
how to do it if you were submitting from a form. Instead just include
the name in the url - something like
<%= link_to_remote g.group_name, :update => "abc", :url => {
:controller => "users" , :action => "showfriendslist", :group_name =>
g.group_name } %>
Look at the html generated by this to check that it is being included correctly.
