  for consistency with type of role used to access it, and action taken there.

    1: \label{Ambiguous_Reference}
    2: This error message has come up when a user tried to look at a resource
    3: in the publication space, while the viewer is not currently in a
    4: class.
    5: 
    6: LON-CAPA's resources are rendered very dynamically, reacting to the
    7: class the viewer is in, where in a sequence they are, whether they've
    8: finished other problems correctly, how many times they've tried a
    9: problem... all of these things are stored as part of the information a
   10: course keeps track of about a student. When viewing resources that
   11: depend on this information to determine how to render them correctly
   12: while not actually in a course, LON-CAPA cannot really determine how
   13: to correctly render the resource. 
   14: 
   15: Rather than simply refuse to show you the resource, LON-CAPA will try
   16: to make reasonable guesses about how you want to view the resource. In
   17: order to warn you that this is not a definitive rendering of the
   18: resource, LON-CAPA displays the warning ``Could not handle ambiguous
   19: resource reference'' to warn you that it's guessing about the
   20: resource.
   21: 
   22: For the same reasons as LON-CAPA cannot ``correctly'' determine how to
   23: render the resource, you will not be able to correctly interact with a
   24: resource viewed with an ambiguous reference. LON-CAPA logs a student's
   25: interaction with a resource in the course information, so if you are
   26: not viewing the resource from inside a course, LON-CAPA has nowhere to
   27: store information about whether or not you've gotten the problem
   28: correct, how many tried you should be allowed, etc, so all input to
   29: the problem will simply be discarded. To test the problem, use your
   30: \textbf{Authoring Space}.
