lifecycle callbacks and ROP

[Tore Halset]

Hello.

I am a lifecycle callbacks newbie trying to understand http:// 
cwiki.apache.org/CAYDOC/lifecycle-callbacks.html in a ROP context.

Can the callback methods be defined in the client PersistentObject or  
only in the server CayenneDataObject?

Can a ROP client perform non-lifecycle callbacks on the server? If  
not, are there any other standard way for a ROP client to call a  
method on the server not related to the persistence lifecycle? Or  
perhaps it is possible to have custom event types not related to the  
lifecycle?
