That is not correct behavior. Bizobjs can have multiple cursor
objects; when a parent bizobj's PK changes, the child's _CurrentCursor
should change to a new one specifically for that parent record. If you
navigate back to the original parent record, it should re-set the
child's _CurrentCursor to the one that was originally associated with
that parent PK.
This is the code in dBizobj:
for child in self.__children:
# Let the child know the current dependent PK
if child.RequeryWithParent:
child.setCurrentParent(pk, fromChildRequery=True)
if not child.isAnyChanged():
child.requery()
So the only way I could see that the child is getting requeried is if
isAnyChanged() is returning False.
Do you feel comfortable doing some testing to figure this out? I
would give you a modified version of the files in question that
includes some debug output lines, and you would run through your app
as you are doing now. Afterwards, send me your observations as well as
the debug output.
