I posted the mapping and the 'execute' and 'addContact' methods:
http://wiki.wendysmoak.com/cgi-bin/wiki.pl?StrutsDoubleRequest
There's nothing special going on. Definitely no custom RequestProcessor.
It's just a LookupDispatchAction that looks at 'userAction' to pick the
method. And at the point you ask it to add a record, it returns
mapping.getInputForward();
Thanks for looking at it. I've stared at it for a while and I just don't
see anything that could be causing that second pass through the Action code.
Could anything other than an actual HttpRequest make the RequestProcessor
say:
Processing a 'GET' for path '/editContact'
?
I'm going to look at all the JavaScript to see if there's something that is
somehow making a second request. (The 2-3 second delay makes me think this
is happening as/after the page is rendered.)

And the answer turned out to be a Filter that called chain.doFilter(...)
twice. JSwat (debugger) exposed the problem in a few minutes.

If you do a form.submit() inside a submit button's onclick handler have
the handler return false. That will prevent a double-submit.

Thanks Nic and David for confirming that I'm not [necessarily] crazy. I do
think it's the JavaScript, and will check that next. It'll probably be
Tuesday before I get back to it though.

Wendy,
I had a similar problem but I was HTML based, not Struts based: The button
in my form was doing a submit but it was also a submit button. The result
was a double submit behavior much like you've shown here.
Can you post the Javascript attached to your <form .... > rendered HTML tag
PLUS any for relevant buttons you click on in your end-result-HTML page?
Regards,
David

Wendy,
I had a similiar issue where I was adding a user, and I would get an
error about breaking unique constraints. Looking at the logs, I saw this
action being performed twice. I don't have an exact solution, but what I
did was re-checked my pageflow (I was using DispatchAction), and made
sure I was returning to the correct page, or none at all to narrown down
the issue. This 'solution' didn't really justify my actions to correct
it, but I haven't had time to go back.
HTH,
- Nic.
