Thanks Jesse. I was looking in the HTTP Protocol and didn't think of
checking the Servlet specification.
For those who are interested, here it is in 4.1 of version 2.4 of the
Java Servlet Specification:
SRV.4.1 HTTP Protocol Parameters
Request parameters for the servlet are the strings sent by the client to
a servlet
container as part of its request. When the request is an
HttpServletRequest object,
and conditions set out in “When Parameters Are Available” on page 36 are
met, the
container populates the parameters from the URI query string and POST-ed
data.
The parameters are stored as a set of name-value pairs. Multiple parameter
values can exist for any given parameter name.

Yeah, this is covered by the servlet container implementors. public
Object[] HttpServletRequest.getParameterValues(String key) {..}
It's how radio groups / multiple select choices / checkboxes all work.

I dont know definitely on what the standard is (specialy because
browsers choose to implement them how ever they want)
but using same name for multiple inputs usualy means array
.. php recognizes this if input name edns with "[]"

Thanks (again), Andreas. You are right and I have found a way that
doesn't require using these pairs. I assumed that the POST protocol
mandated unique names, but I haven't been able to turn up anything
justifying my assumption.
Best regards

Actually, that's the correct behavior... at least that's how it's been since T3!
All the For_0 hiddens values are used during rewind and they're
expected this way
I'm guessing you're trying to do some javascript that relates to those?
Do you really need to use those values? I'd prefer not to tie the js so much
to tapestry's internals...

Hi All
Below is a form snippet followed by the html generated by Tapestry
4.1.5. The LI element ids are sensibly "For_0" through "For_N". The
hidden fields corresponding to these items are ALL named "For_0".
Surely the appended digit should be incremented so as to correspond with
the LI ids?
Am I missing something?
