for err-disc2.py, that one was something stupid. query was great, the mapper wasnt expecting a blank "eager" row for an inheritance relationship, rev 2257. sort of surprised that one hasnt come up before, its been around a long time.

It does not happen if inheritance is not involved.right A and B are no longer
the "same" class if they dont inherit.
Employee points to Dept and Dept points to Director; Director inherits
Employee. no other references.thats not the test case im talking about, you gave
me just "A" and "B"
with "B" point to "A" (which is "A" pointing to "A"). just look at the queries these things generate, expecting eager in all cases from those relations is starting to push the envelope a bit further than I can handle myself (as well as what a DB can usually handle).
is there any link between a relation being post_update and being lazy?no.
