Oops, I found the problem. I should not return anything when I put
things into content_for, so
<code>
def observe_field(field_id, options = {})
#super
#return
if @layout_options
content_for :after_js_ready do
super(field_id, options )
end
return "" # ****** don't return immediate results****
else
super
end
end
</code>
Cool! I am getting A in yslow now :D
