That's an application design issue.
I design my applications so that data is collected and validated elsewhere,
and if all goes well, I then create or modify an existing DataObject,
converting html string form values into proper types, and commit the
changes. If the commit fails, I roll everything back.
Other folks read data directly into their DataObjects, and just keep
recommitting until until it works.

No, there's no explicit locking in Cayenne. However, your datacontext will
contain uncommitted changes.
