Hi, yes, you are right: persistency, history and logging is basically missing. As I presented at Smalltalk Solutions there is some experimental code available that can be made to work with some tweaks, but that approach doesn't seem to work well and scale good enough for the future. I spent some time to rethink the whole concept, and I am definitely planning to spend time to come up with something reliable, but I am simply too busy writing my Master and giving Seaside, Magritte and Pier presentations (almost) all over the world. Again this is more a problem of having the necessary time to do it, than to do the actual implementation. Of course anybody is free to write its own persistency framework, as far as I know some guys at Impara did that and wrote an XML back-end? Cheers, Lukas -- Lukas Renggli http://www.lukas-renggli.ch
