Rails - Mar 2007 - Optimistic locking and update_attributes: not working?

Hi all,

I''ve searched the forumns, but I can''t seem to find an answer
to this
one. I''m having trouble getting optimistic locking (OL) to work in my
app, even though all of the pieces are there:

* table has lock_version column, with default of 0 (zero)
* lock_version column is being incremented by the first update (but the
second doesn''t catch it)
* I''m trapping for ActiveRecord::StaleObjectError, but it is never
thrown

But nothing seems to work.

Note that currently, I''m still in development mode and using the
scaffolding code that relies on update_attributes, but I haven''t found
any documentation that states whether OL works/does not work in
development mode or with update_attributes.

Anyone have an answer for this, and/or code they are willing to share?

Many thanks,

Eric
