jquery ui - Rails getting ActionController::RoutingError (No route matches [GET] "/assets/images/ui-bg_flat_75_ffffff_40x100.png") -


i'm getting following error in rails app (doing request image doesn't exist:):

actioncontroller::routingerror (no route matches [get] "/assets/images/ui-bg_flat_75_ffffff_40x100.png"): actionpack (3.2.12) lib/action_dispatch/middleware/debug_exceptions.rb:21:in `call' actionpack (3.2.12) lib/action_dispatch/middleware/show_exceptions.rb:56:in `call' ...

it looks known error in jquery-ui.css

these sites talk it:

jquery-ui.css images

fixed jquery ui css , image location work minified assets

and

bug report

i have jquery-ui.css in stylesheets folder. version: /*! jquery ui - v1.9.2 - 2012-11-23

line 246 has:

url(images/ui-bg_flat_75_ffffff_40x100.png)

but, don't know how fix it.

any appreciated!

i believe can resolve viewing jquery-ui.css and/or jquery-ui.theme.css , finding line pointing , removing images @ start therefore this. 

url(ui-bg_flat_75_ffffff_40x100.png)

instead of: 

url(images/ui-bg_flat_75_ffffff_40x100.png)

its looking @ wrong path therefore receive error.
