OK, I took core=True off, and added it to the reference_no field. The
problem seems to go away for the case when no there are no
pre-existing joins. Clearly, I don't understand what core is for.
I'll read the docs again, and see if it makes sense.
However, it still errors with
{'jointable.0.id': [u'Join Table record with this ID already exists.']}
when I tried to save a LeftSide records with existing associations.
thanks for any and all help.
