I have a dataset containing a datatable. Everything was working OK. Then I changed the definition
of one of the columns from not null to nullable. Now when I update the adapter, the change is not
being written to the DB.

Just before the update, I looked at the data in the datatable by walking through the datarows, and
it contains the expected value for the row and column I'm interested in. The very next statement is
the Update.

What could be causing this? What tools can I use to diagnose this further?

Thanks, Flomo

If you don't want to manually dig through the generated code, simply 
recreate your command objects for insert and update.

I gave up on this and reverted to an older version which worked.

I am sorry I didn't have time to try the suggestions, but I do thank you for them.
