Display of existing custom field values is now working as part of the MdhRecord object. I've also tested integer and long text fields (which are limited to 8000 characters, but that should be enough). There's a significant performance hit when retrieving a record from the database if you retrieve the custom fields as well, because you have to retrieve the list of field types, and then the list of instances for that document record, so I've made the retrieval of custom field instances an optional parameter on populateFromDb*() methods, which is false by default. This means they'll only be retrieved when a record is being displayed in full (or edited, although the edit code is not written yet).
