------------------------------------------------------------------------------------------------------------------
Key: OPENJPA-451
URL: https://issues.apache.org/jira/browse/OPENJPA-451
Project: OpenJPA
Issue Type: Test
Affects Versions: 1.0.0
Environment: Windows Vista, Intel Core 2 Duo, 1gb RAM
Reporter: Sebastian Souza
Priority: Minor
This is the case
Class Item {
private Collection<Attribute> attributes;
}
Class Attribute {
private Item item;
private Data data;
}
Class abstract Data {
public abstract Object getValue ();
public abstract void setValue (Object value);
}
Class DataString extends Data {
private String value;
public Object getValue () {return this.value;}
public void setValue (Object value) {this.value = (String)value;}
}
In my orm.xml i declare
<mapped-superclass class="Data">
<entity class="Item">
<attributes>
<one-to-many name="attributes" target-entity="Attribute" mapped-by="item">
<cascade>
<cascade-persist/>
</cascade>
</onte-to-many>
</attributes>
</entity>
<entitiy class="Attribute">
<attributes>
...
<embedded name="data">
</attributes>
</entity>
<embeddable class="DataString">
<attributes>
<basic name="value">
<column name ="data"/>
</basic>
</attributes>
</embeddable>
Data is persisted in Attribute table, so it has to be an embedded field
When i try to commit an Item in
getTransaction ().commit ();
239680 ITSM TRACE [main] openjpa.Runtime - An exception occurred while ending the transaction. This exception will be re-thrown.

If i change my code to
Class Item {
private Collection<Attribute> attributes;
}
Class Attribute {
private Item item;
private DataString data; // Reference to a specialization class
}
Everything works fine!

[jira] Commented: (OPENJPA-451)
org.apache.openjpa.util.GeneralException: null at
org.apache.openjpa.kernel.BrokerImpl.embed(BrokerImpl.java:2645)

[ https://issues.apache.org/jira/browse/OPENJPA-451?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12606432#action_12606432 ]
Pinaki Poddar commented on OPENJPA-451:
---------------------------------------
Attribute class has declared a field named 'data' of type Data. And Data is a MappedSuperClass.
According to JPA specification, however, "a mapped superclass cannot be the target of a persistent relationship".
Attribute.data is a relationship which may or may not be embdded from a mapping perspective.
This may explain why when type of the field 'Attribute.data' is changed to DataString which is a *not* a mapped superclass -- everything works.
