I don't think this made it into the official code. It was part of
the tail-end of the last active Cayenne project I worked on before
politics changed that project from Cayenne to JPA.
I think I decided not to pursue it because (1) I wouldn't be around to
maintain it, and (2) there was already ongoing discussion about the
best way to allow modeler extensions.
The actual changes to allow extensions is pretty simple and small,
although "detecting" extensions in this version involves specifying an
"org.apache.cayenne.modeler.cayenneActionPluginFactory" System
property and including your extensions in the classpath.
But at the time, it worked well enough for my purposes.
I haven't followed the modeler development closely since then (2007?)
so I am not sure what, if any, extensions points currently exist. My
guess is that it would be easy for you integrate this into the current
code base -- really, it's a quick easy hack to add menu items to
various modeler menus.
