Ok, I tried bumping up the debugging. When saving a new "Make" object
(with no associated Models or Options) I get the following (only
showing info relevant to Models and Options):
<field name="models"
persistence-modifier="persistent"
null-value="none"
default-fetch-group="false"
embedded="false"
unique="false">
<collection element-type="net.uidl.carsales.Model" embedded-
element="false">
</collection>
<field name="options"
persistence-modifier="persistent"
null-value="none"
default-fetch-group="true"
embedded="false"
unique="false">
<collection element-type="java.lang.String" embedded-element="true">
FINE: Object "net.uidl.carsales.m...@5b8e8c" field "models" is
replaced by a SCO wrapper of type
"org.datanucleus.sco.backed.List" [cache-values=true, lazy-
loading=true, queued-operations=false, allow-nulls=false]
FINE: options : null
18/08/2009 12:42:58 org.datanucleus.ConnectionManagerImpl
allocateConnection
And when loading a make I get the following:
FINE: Object "net.uidl.carsales.m...@1be996d" field "models" loading
contents to SCO wrapper from the datastore
18/08/2009 13:04:27 org.datanucleus.ConnectionManagerImpl

FINE: Connection found in the pool :
