-------------------------------------
Another related issue - the ability to redefine entity listeners (and
callbacks?) per project. Often it makes sense to define entity mapping in a
common "library" project shared by many applications, but defer listener
definitions to individual applications. This way the listeners can have
application-specific logic. Currently this is possible to achieve via API, but
ideally this should be done via mapping. What this means is the ability to
merge two obj-entity definitions into one.
