Re: T5: Tapestry, Hibernate and Underscores.
I did not. The problem was not with hibernate. The problem was that you used hibernate annotations (JPA annotations, actually) in a way other than their documented intent. If you annotate a field _foo, then the property name will be _foo according to hibernate, regardless of accessors. You can override the automatic column designation with @Column but by default, it'll look for a column named _foo. You can also solve it by either annotating the getter (as mentioned elsewhere), or by renaming your variable to not use the _. Where am I misunderstanding? My comments about tapestry were only that you could avoid using _foo style and tapestry would continue to work. Anyway, this is a hibernate configuration question, not a tapestry question, so we should kill this thread on this list anyway. Christian.
