thx gavin, that is good news and will solve the data-structure-problems: And it looks like a good idea anyway to have an intermediate layer for ui-datastructures anyway. Will it still be richfaces-dependent or are you striving to make this a common layer that can be exchanged between several ui-frameworks (e.g. icefaces, myfaces/adf etc)?! ok, maybe I'm dreaming a little here...
