I'm using dynamic-entity MAP mode. I have an entity with a collection (bag) mapped. When I do a load() (and get() and merge()), the returned map keeps coming back with null in the collection key value.

The entity map does get load ok with the collection if the entity is returned in a query though.

Any thoughts anyone? Thanks much.

Versions:
3.2.2, 3.2.6

Mapping documents:

<class entity-name="UserEntity" table="USERS">
<id name="id" type="java.lang.Long" column="USER_ID">
<generator class="native"/>
</id>

<version name="version" access="field" column="_OBJ__VERSION_"/>

<bag name="itemsForSale" inverse="true" cascade="merge,delete">
<key column="USER_ID"/>
<one-to-many entity-name="ItemEntity"/>
</bag>

...
</class>

Code between sessionFactory.openSession() and session.close():

Long id = ...;

Map persistentMap = (Map) session.load("UserEntity", id);

then, in persistentMap, the value for key "itemsForSale" is null.

and yes, there is data in the database...

thanks in advance.

load doesn't usually return null if an object is not found as it will throw an exception when you try to access properties of the non-existent object. Session.get however will return null if the object you requested isn't found in the database.

Nonetheless, have you tried something like:

UserEntity entity = (UserEntity) session.load(UserEntity.class, id);
