I'm using IBO to create a multi-user app and I'm facing some problems
re multiple users looking/editing the same record simultaneously.

Scenario 1
User A and B both looks at the same data. User A clicks 'Edit', user
B also clicks 'Edit'. I understand that I can prevent that by using
the pessimistic locking option in IBO, and it seems to work.

Scenario 2
User A and B both looks at the same data. User A edits and save the
data. User B now clicks 'Edit'. Ideally, I would like to (re)fetch
the updated data to the user so that the latest changes are visible.
What is the best method to do this?

Thanks in advance.

Regards
Ray
