[Mono-list] Strange Error When Populating A DataSet

[David P. Donahue]

Well whaddya know, that worked :)

Of course, this came in just in the middle of my compiling and upgrading 
to 1.1.5, as suggested by someone else.  I'd hoped to stay out of the 
development tree for my production server, but everyone seems to be 
agreeing that 1.1.5 is kosher and I could probably use any performance 
increase it brings.  Hopefully my upgrade won't break things now that 
you've fixed my last known bug :)


Thanks,
