Hibernate issues inserts that cause constraint violations when using session.replicate
--------------------------------------------------------------------------------------
Key: HHH-2540
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2540
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.0.ga
Environment: Hibernate 3.2.0, JBPM 3.1.4, Oracle 10.2.0.2.1
Reporter: Scott Clasen
When using session.replicate to replicate a JBPM ProcessDefinition from one data store to
another, hibernate does not do "the right thing" when it creates insert
statements to insert the process definition into the destination data store.
There are two nullable columns with foreign keys, FK_PROCDEF_STRTSTA and FK_NODE_PROCDEF
that mean ProcessDefinition must have a StartState, and a StartState must have a
ProcessDefinition
here are the relevant mapping snippets.
<hibernate-mapping default-access="field">
<class name="org.jbpm.graph.def.ProcessDefinition"
table="JBPM_PROCESSDEFINITION">
<!--other mappings omitted-->
<many-to-one name="startState"
column="STARTSTATE_"
foreign-key="FK_PROCDEF_STRTSTA" />
<!--other mappings omitted-->
</class>
</hibernate-mapping>
<hibernate-mapping default-access="field">
<class name="org.jbpm.graph.def.Node"
table="JBPM_NODE"
discriminator-value="N">
<!--other mappings omitted-->
<many-to-one name="processDefinition"
column="PROCESSDEFINITION_"
foreign-key="FK_NODE_PROCDEF"/>
<!--other mappings omitted-->
</class>
</hibernate-mapping>
In the usual case of saving a ProcessDefinition, hibernate does the correct thing and
inserts null for each of these foreign key columns, and then later updates these
columns...like so
2007-04-02 14:22:07,863 DEBUG org.hibernate.SQL - /* insert
org.jbpm.graph.def.ProcessDefinition */ insert into JBPM_PROCESSDEFINITION (NAME_,

more inserts follow and then later in the same transaction...sets the foreign key for
start state.

When using session.replicate to copy a fully initialized object from a source to a
destination data store...hibernate does not set the start state to null and then later
update...it just tries to do the insert and gets a constraint violation
