I think the problem you are having has already been fixed in cvs
Branch_3_0 and HEAD. The problem was that fields set after a finder was
executed were not stored.
As for debugging the first thing it to increase the log level of
org.jboss.ejb.plugins.cmp to TRACE. The classes called when you set a
CMR field are (off the top of my head)
org.jboss.ejb.plugins.cmp.bridge.EntityInterceptorBridge.invoke
org.jboss.ejb.plugins.cmp.jdbc.bridge.JDBCCMRFieldBridge.setValue
At this point it goes through the interceptor stack of the related entity.
Then it falls back through.
