def getPK(self):
""" Return the value of the PK field."""
if self.KeyField is None:
raise dException.dException, _("No key field defined
for table: ") +
self.DataSource
cc = self._CurrentCursor
return cc.getFieldVal(cc.KeyField)
I believe that
return cc.getFieldVal(cc.KeyField)
returns an exception because parent.RowCount =0
but the app continues to run.
As I see it the method should return something that will still allow the
requeryAllChildren to complete. As to what I'm not sure. I will have to
leave that to better minds than mine.
