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

Have seen a few people getting this after searching the mailing list - I'm
wondering whether writing my own entity sorter might be the quickest route
to a fix as soon as I can dedicate some time to it!

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!
