Hi
I have class mapped this way
<class name="Message" table="MESSAGE" mutable="false" batch-size="30"
lazy="false"
>
<cache usage="read-only"/>
<id name="id" column="MESSAGE_ID" type="int">
<generator class="assigned"/>
</id>
<property name="key" column="MESSAGE_KEY" type="string" length="500"/>
<map name="submessages" table="V_SUB_SERVICE_MESSAGE" batch-size="10"
lazy="false"
>
<key column="Message_ID" />
<map-key column="SUB_SERVICE_TAG" type="string"/>
<element type="string" column="Message_Value" />
</map>
</class>
One of the instances of Message has a collection of submessages with only
one entry, wich has a null on the Message_Value column.
Using 3.0.5, I can efectively retrieve that instance with his one element
map. When I ask for that only key I get the expected null value.
But using 3.1 rc2 that map is empty. The null valued key is no longer
loaded.
Is this a known issue? If it's not I'll try to give an example to reproduce
it.
Cheers
Emilio
