what could be a reason for my js to be displayed on the screen for a  
second before it catches and does what it’s supposed to? I’ve had this  
happen when I call page.reload inside render :update block…

\<%= link\_to\_remote ‘reload’,  
:update =\> ‘my\_div’,  
:url =\> {:action =\> ‘reload\_page’} %\>

def reload\_page

respond\_to do |format|  
format.js do  
render(:update) do |page|  
page.reload  
end  
end  
end

end

yup, rails newb.

Don’t pass :update to link\_to\_remote if you’re using render :update
