There was a post in microsoft.public.dotnet.framework.adonet about an
exception thrown when objectdatasource.update() is called by Markus (no
other names ). Kevin Yu [MSFT] answered that he'd answer in this
newsgroup. I saught the messages posted so far but I couldn't find his
answer. Neither ObjectDataSource, nor Update(), nor Kevin Yu (or just
Kevin) as a sender returned a result.
