In the Castor 0.9.5 examples (the JDO Example) I've the OQL Query Analyzer GUI tool
and tried to run the query:
SELECT o FROM myapp.Product o WHERE product.group.id=3
I get an exception:
org.exolab.castor.jdo.QueryException: An unknown field was requested: product.group.id
(myapp.Product AS prod)

...
Am I asking the wrong question (in which case how should the query be formulated)?
Or is there a problem with my database (HypersonicSQL)?
Or is it a bug?
:-)
