TAP5-920 rears it's head again in 5.2 with a twist
TAP5-920 has long been an issue for one of our applications which uses
composite keys.
https://issues.apache.org/jira/browse/TAP5-920
In the past we have worked around the issue by providing an encoder
with our affected loops.
We are now working on upgrading from 5.1.0.5 to 5.2.4 and have run
into a new problem:
Even if we supply an encoder, the default encoder
(HibernateEntityValueEncoder) gets used and the NPE is back.
Below is a stack trace. Suggestions?

My brute force workaround was to disable
tapestry.hibernate.provide-entity-value-encoders in
AppModule.contributeApplicationDefaults.

I've run into this issue now myself, was there ever a resolution to this
or a workaround? As David said, supply an explicit value encoder isn't
able to solve the issue for me either.
Thanks,
Rich
