Charles,
Currently Castor does not allow complex objects (e.g. UserInfo) to be
used as primary keys. However, the UserInfo's identity could certainly
be used as part of the compound primary key if it was mapped as the
reference (that is, instead of the whole UserInfo object being mapped,
only map the identity field). However, doing this means that you'd need
to manage the relationship between the Match object and the UserInfo
object by hand. Castor does not manage such a scenario.
