Subject [jira] [Created] (OPENJPA-2117) XML overriding column names for 1xM attributes causes exception.
Date Thu, 26 Jan 2012 18:20:38 GMT
XML overriding column names for 1xM attributes causes exception.
----------------------------------------------------------------

                 Key: OPENJPA-2117
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2117
             Project: OpenJPA
          Issue Type: Bug
          Components: jdbc
    Affects Versions: 2.1.1, 1.2.3, 2.0.2, 2.2.0
            Reporter: Albert Lee
            Assignee: Albert Lee
             Fix For: 2.2.0


Entity with 1xm relationship define in orm.xml causes the following exception during emf.createEntityManager.

+    //Removing the XML from the orm.xml file, and using this fixes the issue:
+    //@OneToMany(fetch=FetchType.LAZY,cascade=CascadeType.ALL)
+    private List<XMLManyToOneEntity>  xmlManyToOneList = new ArrayList<XMLManyToOneEntity>(0);

And this mapping in the orm.xml:

+              <one-to-many name="xmlManyToOneList" fetch="LAZY">
+            <join-column name="IDENTITY" />
+                 <cascade>
+                    <cascade-all/>
+                 </cascade>
