Is there a render :alert to make a popup box display from the  
controller? Or anything similiar? Just grasping at straws. I know there  
has to be a way to do this. I am trying to get a popup box to show if a  
validation check fails. Thanks,

~S

I would just do this using RJS:

render :update { |page| page.alert “alert message” }
