What would cause a raw_id_admin field to have a proper ID number in it,
but not be able to:
1. display the __str__() of the chosen object beside the input field
2. render the usual list of objects when clicking on the hour glass
The hourglass link shows "http://((server))/admin///", which is
obviously not correct.
Is this a known issue with a known workaround, or have I created truly
stupid and evil objects (code snippet below)? Also, without the
try/except clause in __str__() on the invoice object, I get a horrid
traceback when trying to load the payment object in the admin
(traceback snippet below). Note that if I take out the raw_id_admin
part, there's no traceback.
Enlighten me!
