Hi Mike, Would be cool to have you back :-)
Yeah, my estimate re: horizontal+vertical inheritance was that it would require lots of *uninterrupted* work on my end (lets say 4 weeks). Since I have to work on other projects at the same time, that's the luxury I can't afford (in fact it already resulted in a few abandoned local git branches where I started to develop some idea, only to realize I can't remember what it was when I come back to it 2 months later).
I am going to WWDC in a few weeks. Maybe I can use this "vacation" time to give it another shot (especially since it involves a trans- atlantic flight where nobody can call me or send an email ... this may be equivalent to 4 weeks of office time :-)). I was going to work on some other 3.1 features now, but since inheritance has always been high on my list of things to do, I wouldn't mind re-prioritizing...

Andrus, In the horizontal inheritance jira issue, you mentioned the following: ================= Unfortunately we dropped the ball on horizontal inheritance in 3.0 due to the lack of time by people who could make it happen (the implementation is rather deep and involved). I very much like to revive this effort in 3.1 beyond a few Modeler patches that we have in place so far. It is in my queue right after the new DI stuff. ================= The primary JSF/JPA team project I have been working on is now considering switching to Cayenne and dropping JPA. One of the concerns is vertical inheritance support. Any thoughts on how long it might take and how much effort is involved before vertical inheritance is a first-class citizen? If we switch, it is likely that I will be able to contribute toward this effort -- it was hard to find time to work on Cayenne when I wasn't doing any paid projects involving Cayenne.
