use property names defined in CompositeUserType as default column names
-----------------------------------------------------------------------

                 Key: ANN-640
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-640
             Project: Hibernate Annotations
          Issue Type: New Feature
    Affects Versions: 3.3.0.ga
            Reporter: Michael Newcomb
            Priority: Minor


Consider:

public class LongitudeLatitude
{
  protected double longitude;
  protected double latitude;
}

public class LongitudeLatitudeCompositeUserType
  implements CompositeUserType
{
  public String[] getPropertyNames()
  {
    return new String[] { "longitude", "latitude" };
  }

  public Type[] getPropertyTypes()
  {
    return new Type[] { Hibernate.DOUBLE, Hibernate.DOUBLE };
  }

  ...
}

@Entity
public class Test
{
  @Basic(optional = false)
  @Type(type = "foo.bar.LongitudeLatitudeCompositeUserType")
  @Columns(columns = { @Column(name = "location_longitude"), @Column(name = "location_latitude") })
  protected LongitudeLatitude location;
}

Why does the developer need to specify each column?

I'd really rather let the CompositeUserType take care of that for me. Now, I have to tie the @Columns to the # of properties in my CompositeUserType AND the order in which they are defined? This seems to defeat the purpose of having a class (CompositeUserType) to tell Hibernate how to store it.

Couldn't Hibernate prepend the property name 'location' and '_' to the front of each property name in the CompositeUserType?

Perhaps (more than likely) I'm doing something wrong, but I get a failure if I do not specify the columns.

Thanks,
Michael
