Hello, I'm really sorry for how long it took to respond to this - sadly did not have time to look into it further due to time constraints at work.
The problem still exhibits itself - I've rebuilt Cayenne 4 a couple of times - I'm also seeing it manifest with the following exception: Caused by: org.apache.cayenne.CayenneRuntimeException: [v.4.0.M3-SNAPSHOT Jan 12 2016 15:08:09] Can't extract a master key.

It occurred to me that others may have their own implementations of Ashwood or other entity sorters - anyone up for sharing? Or perhaps has there been any news as regards a potential fix for this? Thanks all! -- View this message in context: http://cayenne.195.n3.nabble.com/Erratic-AshwoodEntitySorter-NPE-on-Latest-Snapshot-tp4027453p4028225.html Sent from the Cayenne - User mailing list archive at Nabble.com.
