Exception Type: ProgrammingError at /admin/businessPartner/entry/33/
Exception Value: operator does not exist: integer = text[]

                                                          ^
HINT:  No operator matches the given name and argument type(s). You might need to add explicit type casts.

I added some print statements near the offending cursor.execute and for get_db_prep_lookup (note: expect line mismatch in traceback), here are the results:

exact pk= [u'33']
exact pk= [[u'34']]
sql=SELECT 1 FROM "table" WHERE "id"=%s
params=[[u'34']]

clearly the found pk is being put on a list that breaks stuff. The models don't use any custom fields. The SELECT statement refers to the first of inline-edited objects.

SVN r7249.

I think I managed to fix it myself. Please check.

[Malcolm Tredinnick]

It's impossible to evaluate this fix without having some way to repeat the problem. Since edit_inline isn't completely broken, there must be something about your particular case that is special. Please construct a very short example pair of models and describe how to replicate the problem.

Closing this ticket since its deprecated with newforms-admin. If it doesn't work there as well, feel free to open a new one.

sorry, didn't mean to do that as Anonymous Coward
