Normally the desired functionality is somehow related to one of the fields, but if that is not the case, you could presumable use a virtual field to attach the commit-processor to. As a sidenote. I have not actually ever done precisely that, but I did do it with get- and set-processor on a virtual field, and that does work. E.g. rather than making a function or so, calculating the 'age' from the birthdate can be done by an extra virtual field, which is simply implemented by a set- and getprocessor: http://cvs.mmbase.org/viewcvs/src/org/mmbase/datatypes/processors/Age.java?view=markup Actually, that is an alternative for overriding setValue and getValue in an MMObjectBuilder extension, but you can use bridge and so on, which I like better.
