[xwiki-devs] Event for document loading?

Hello XWiki devs, I was wondering if there is an Event which gets published when an XWikiDocument first gets loaded, or a good way of adding such an event? I have been looking for such an event, but one does not appear to exist and to add one looks like it would require making changes to the XWikiHibernateStore to have it fire events on load. I am looking for a way to intercept documents when they are first being loaded so I can populate some of their objects from an external source and avoid the issue of having many joins when working with documents with a large number of objects. My other thought is to use a custom hibernate mapping to get this data for a custom table I can populate in other ways, but I would prefer the event driven approach. Thanks! ~Vincent
