Hi,
I'm encountering a problem in my app where users are double submitting a
form, creating a hibernate exception in the back end where two
sessions are attempting to update the same collection. I've read some
posts about preventing form resubmission by using a unique token in the
form to detect a double submit.
If a double submit is detected, the second and subsequent submits wait
until the original one returns and then report the outcome of that
transaction (if I understand correctly, it's the last submit that issues
the response to the user, and the first one does the updating).
I'm wondering
a) is this indeed the right approach to stop users who are
over-enthusiastic in their button clicking from encountering errors, and
b) does anyone have an actual example of code that implements this pattern?
Thanks very much
Denis Mc.
