    Rather than passing your actual domain objects (EntityObjects) to the view, you may want to use your controller to map them into a Model object that better represents what your view should actually be displaying. This will reduce the amount of logic required in your View, and have the pleasant side-effect of avoiding passing EntityObjects around after their context has expired.

    Edit based on your edit:

    No, the API doesn't have a way to take a single Entity Object and make every other Entity Object of its type which was loaded at the same time it was be lazy-populated with a particular property in one fell swoop. You are better off pulling all of the items out in the first place using the Include mention like you show in your question.
