Hi,     I am calling on action using render_component,in that action i am again calling one javacritp function.when i am execute this code the script is not working,my code is here.

my view goes here: rating : <%=render_component(:controller=>'products',:action=>'star_display',:params=>{:product_id=>2})%>

action is def star_display   product_id=params[:product_id]   overall_rating=ProductRating.find   rating=overall_Rating end

My star_display view is <img src="/images/star1.gif" id="star1"> <img src="/images/star1.gif" id="star2"> <img src="/images/star1.gif" id="star3"> <img src="/images/star1.gif" id="star4"> <script language="javascript" type="text/javascript"> showAllStars(<%=@rating%>); </script> here the script is not working.but if i print anything inside of the script tag it gets printed means the action executed successfully but the script is not running.i don't know what's the reason please anybody help me.

thanks, Bala

You don't seem to be setting @rating in your action. Have you tried
using firebug to step through your javascript and see where it is
failing ? (oh and render_component is deprecated and very rarely the right thing
to do)
