Problem with @Embedded and @AttributeOverrides

Using hibernate-annotations-3.2.0-GA.

When using an @Embedded composite element, and overriding the column names like this:

Code:

@Embedded
@AttributeOverrides( {
    @AttributeOverride(name="extention", column = @Column(name="phone1_ext") ),
    @AttributeOverride(name="number", column = @Column(name="phone1_number") )
} )
public PhoneNumber getPrimaryPhone() {
    return _primaryPhone;
}

The schema generator does not obey to the the other annotations in the embedded class. For example:

Code:

@Embeddable
class PhoneNumber {

    @Basic
    @Length(min=0,max=6)
    public String getExtention() {
        return _extention;
    }

}

In this case, the resulting schema looks like:

Code:

phone1_ext varchar(255),

The lenght should be 6, not the default 255.

I don't see any way to override any other annotiation beside the @Column, and in fact, I would prefer not having to do it. Any suggestions?

Thank you.

Hi,
The @AttributeOverride annotation takes a @Column annotation as an argument. In the sample you sent you set only the @Column's name
argument, but all other arguments of the @Column have default values, for example:

The default value for length is 255 (see ejb-3_0-fr-spec-persistence, page 168). So you actually did mentioned a value for the column's length - 255.

BTW @Length is an Hibernate validator annotation, not an ejb3 annotation. If you only wanted to set the column length (rather than to use the validator) you should use the @Column from start.
