Hey Richard,
What version are you using of:
the integration module
Tapestry
Cayenne
?
Also, can you tell me what the actual exception was?
Robert
tapestry5-cayenne-core (and -server) 0.4
Tapestry 5.2.6
Line of code that threw the exception:
model = beanModelSource.create(BaseObject.class, true,
resources.getContainerMessages());
And the exception to where it hit my code:
java.lang.NullPointerException

This isn't something I would want backed by Cayenne. I would probably
stick it in JCR or something, but there would be pieces of the
application I would want to use Cayenne. I have not had a chance to look
at how to not use the Cayenne piece for parts of the application.
