Hi Robert,

Cayenne gives you a little more information that Hibernate, it that
you can get all the DbAttributes assocated with an CayenneObject, e.g.
the maximum string/varchar length.

If you are doing very generic code, it can be useful to add a public
accessor method to get at the internal Cayenne map of properties.

regards Malcolm Edgar
