[Seaside] [ROE] Some Questions

Hi guys,

If you got it out of Sourceforge CVS, then yes, that's definitely the
latest version.  I haven't done any work on it for a while (too many
projects...).  There's no documentation, and if you've managed to make
heads or tails of it, well done ;).  If you felt like writing up a short
tutorial, of course, that would be wonderful.

Interesting, I've never seen that (all the tests were green for me).  I
wonder if it has to do with postgres version... what does the query look
like that produces that error?

Yes, that's correct.  Currently Roe deals only with SELECT statements.  If
you have any ideas as to how other operations should work, let me know.

Great.

Yes, maybe I should... it's just so far from being finished or
documented, and clearly people who are sufficiently motivated can find it
;).

Anyway, I'll be very interested to hear your experiences with using it -
you're getting to be the very first users, since I don't even use it for
anything myself, yet...
