The suggestion was for you populate the stash near the end of the request,
before calling out to your view, so as to avoid doing the work when it is
not necessary.  That's why he suggested an ActionClass, or the end method.

Remember, the view is typically called from within the end() action, or form
an ActionClass like RenderView, which itself runs during the "lifecycle" of
the end() action.
