You're doing fine :-) (I once heard someone say that they talk to
themselves because that's the only way they're guaranteed an intelligent
conversation :-))
Not trying to be a pain, but custom db attributes are an either/or
situation (either you have custom db attributes and nothing else, or the
"standard" method of creating the list of attributes and no custom
attributes), at least according to my reading of SelectTranslator. Am I
missing something, is SelectTranslator incorrect in implementation
(compared to your expectation at least), or are you thinking of something
else?
Sorry to be difficult so near to the end of the week ;-)
