This happens when _convert_key() is called with key='arbeitsmittelhierarchy_arbeitsmittel_view.stammdatenverwaltung_tauglich' When I look at the self._ResultProxy__keys then the key cache contains shortend col names: (Pdb) for x in self._ResultProxy__keys:print x arbeitsmittelhierarchy_arbeitsmittel_view_idautor arbeitsmittelhierarchy_arbeitsmittel_view_idsachgebiet arbeitsmittelhierarchy_arbeitsmittel_view_num_hre arbeitsmittelhierarchy_arbeitsmittel_view_bemerkung arbeitsmittelhierarchy_arbeitsmittel_view_versionsnr arbeitsmittelhierarchy_arbeitsmittel_view_idzielgruppe arbeitsmittelhierarchy_arbeitsmittel_view_idfassung arbeitsmittelhierarchy_arbeitsmittel_view_dateiname arbeitsmittelhierarchy_arbeitsmittel_view_originalname arbeitsmittelhierarchy_arbeitsmittel_view_rechnerstand arbeitsmittelhierarchy_arbeitsmittel_view_id arbeitsmittelhierarchy_arbeitsmittel_view_hidx_master arbeitsmittelhierarchy_arbeitsmittel_view_stammdatenverwaltung_ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Using SA 0.3.8 and Postgres 7.4.7...what's the suggested way to get around this issue (shortening the column names isn't an option).
