[hibernate-issues] [Hibernate-JIRA] Created: (ANN-477) @Formula doesn't work in entities referenced by @JoinColumn(referencedColumnName="...")
@Formula doesn't work in entities referenced by
@JoinColumn(referencedColumnName="...")
---------------------------------------------------------------------------------------
Key: ANN-477
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-477
Project: Hibernate Annotations
Type: Bug
Versions: 3.2.0.ga
Reporter: Salvatore Insalaco
Attachments: ProvaBug.zip
See the attached test (build with ant, place hibernate libraries in lib, run test.Test).
Entity Second has a @Formula property.
Entity First has a many-to-one association with Second, not on the primary key but on the
ALT_ID column, using the "referencedColumnName" attribute of the @JoinColumn
annotation.
This is NOT the case of an association to a @Formula column (not supported), but a
relation on a non-primary column of an entity that happens to have a @Formula property.
During SessionFactory creation an exeption is raised:
java.lang.ClassCastException: org.hibernate.mapping.Formula
at org.hibernate.cfg.BinderHelper.findPropertiesByColumns(BinderHelper.java:234)
at
org.hibernate.cfg.BinderHelper.createSyntheticPropertyReference(BinderHelper.java:106)
at org.hibernate.cfg.FkSecondPass.doSecondPass(FkSecondPass.java:63)

at
org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:286)
at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1210)
The bug lies in BinderHelper.findPropertiesByColumns. In the iteration starting at line
233, it tries to find the property that maps the "referencedColumnName", but it
doesn't consider that some properties may not have a Column, only a Formula.
The correct version should be something like this:
Iterator columnIt = property.getColumnIterator();
while ( columnIt.hasNext() ) {
Object next = columnIt.next();
if (next instanceof Column) {
Column column = (Column)next;
if ( columnsToProperty.containsKey( column ) ) {
columnsToProperty.get( column ).add( property );
}
}
}
