--------------------------------
Summary: Graph-based Sorter Attempting Inserts in Wrong Order
Key: CAY-2688
URL: https://issues.apache.org/jira/browse/CAY-2688
Project: Cayenne
Issue Type: Bug
Components: Core Library
Affects Versions: 4.2.M2
Reporter: Peter Hvass
Stack trace below - the graph-based sorter appears to be trying to insert a
child before a parent - but this is happening non-deterministically (i.e.: some
sessions & some users it happens - others not). I haven't managed to reproduce
it myself directly - just pulling logs from errors our users have faced today
in production. :)
I'm not sure of the extent of the info you might need relating to the affected
part of the schema - entities at play - let me know and I will update
accordingly and very much happy to help investigate further.
