Handling of columns with database side default values
-----------------------------------------------------

                 Key: HHH-3180
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3180
             Project: Hibernate3
          Issue Type: New Feature
    Affects Versions: 3.2.6
         Environment: Hibernate 3.2.6
Oracle 10i (should not matter)
            Reporter: Heinz Huber
         Attachments: generated-default.zip

Reload default columns after insert.
Effect: If a component is mapped with generated=default, it will be inserted (unless dynamic-insert and value == null) and then reloaded.
Example: 
	<class name="Verfueger" table="ELVFGR" dynamic-insert="true" dynamic-update="true" select-before-update="true" optimistic-lock="dirty"
		rowid="rowid">
		<composite-id name="nummer">
			<key-many-to-one name="mandant" column="vfMand" />
			<key-property name="anlagekennzeichen" column="vfAkzV" />
			<key-property name="nummer" column="vfVfNr" length="6" />
		</composite-id>

		<property name="sms" column="vfSmsB" generated="default" />
	</class>
If property sms has a value, it will be inserted.
If not, the default value will be set by the database.
In both cases, the value is reloaded after the insert.
