If there are no assets, what is `asset` set to? Clearly it's set to nil right now, but what did you think it should be set to, and why? <h1>Listing Assets for <%= @feature.try(:engtitle) %></h1> What is the exception being raised here? Please show the controller so we can tell what is being set up for the view.
