[hibernate-dev] Envers compile issue

I just made a change to help catch runtime problems that kept cropping up. The change was to org.hibernate.mapping.Value#getColumnIterator. The problem is that code in many modules (hem, envers) that actually deals with mapping code were making a bad assumption here. The returned iterator actually returns a Iterable<Selectable>, not Iterable<Column>. Selectable is the contract shared between Column and Formula. So when code non-defensively tries to treat that thing as a Iterable<Column> we often have issues. Yes, the method is very poorly named. Actually it predates formula as a feature. But be that as it may, the code casting those elements to Column are just wrong. For envers, I am not actually sure how to handle Formula elements. I need some help there. The issues are all isolated to org.hibernate.envers.configuration.internal.metadata Could someone more familiar with envers (and especially its entity definition stuff) take a look? Thanks!
