        Key: HB-461
    Summary: Mapping of formula-based properties
       Type: Bug

     Status: Closed
   Priority: Major
 Resolution: WON'T FIX

    Project: Hibernate2
 Components: 
             core
   Versions:
             2.1

Environment: JDK 1.4, WinXP Professional, Tomcat 4.1

Description:
When I try to define a mapping with a formula-based property I get the following exception:

net.sf.hibernate.MappingException: property mapping has wrong number of columns: net.sf.hibernate.mapping.Subclass.history
at net.sf.hibernate.mapping.PersistentClass.validate(PersistentClass.java:237)
at net.sf.hibernate.cfg.Configuration.validate(Configuration.java:555)
at net.sf.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:712)
...

The property mapping looks like:

<property name="value" formula="myfunc(VALUE)"/>

This happens with Hibernate 2.1 beta 6. When I change the mapping to

<property name="value" column="VALUE"/>

everything works.
