When I defer freezing of the aggregate the thawing doesn't work. When everything gets defered, you have to walk the whole defered list again, for simple types too, which already would have been done. Then in another run, the marker has to get cleared. *If* that works it still adds extra complexity to DOD. > Dan leo
