Comment:
Here is a patch on top of the 2.1 branch on 12/6/2003.
A not-null="true" component will raise a PropertyValueException if null.
A not-null="false" component having not-null="true" sub component will also raise a PropertyValueException to be consistent whith the property behavior.
component, dynamic-component, composite-element and nested-composite elements allow this functionality.
Tests in the patch are hugly but do their job (dynamic-component not tested however).
Changes:
Attachment changed to notnullcomponent.hib2.1.patch

Description:
Component not null
When all properties of component have null value
Hibernate not instantiate that class. It will be nice to be
able define will or will not component be instantiated in
case all properties are null.
For example if there are no values of
columns "address_city" and "address_street" but
address must not be null the instance of Address class
must be assigned to property Enterprise.address.
<class name="Enterprise">
<property name="name"/>
<component name="address" class="Address"
<b>not-null="true"</b>>
<property name="city" column="address_city"/>
<property name="street" column="address_street"/>
</component>
</class>
With best regards.
