Leons posting about the scopes reminded me of something I have been meaning to

Both are good solutions, and I'm looking into both of them.

Ok I made it using the servletcontext like you have said :-), with this

What kind of validation do you use? Serverside or js?
I suppose it happens because the validation-whatsoever send the user

I should have said this first, but why are you calling "makeWidgets"

Hi Dave,
Thanks for your answer.
I know that getParameters().get("myParamater") returns an array of objects,
but isn't it supposed to return not only String[], but arrays of Objects
depending on the type described (if described) for the parameter through
getter and setter in the action : if getId
If you set "executeScripts" to "true", in the submit tag, you can put a
javascript section in the returned page, and it will be executed, like:
makeWidgets();
There is an example if this in showcase, in the remote div section.

You can make your keys comparable [1] or put your results in a
collection that does not try to re-sort them.

Hi Andrew,
I ran into similar problems. Anoter developer on
the team wrote a tag. It extracts the paging
information and goes to the database table to find out
the total number of records.
The tag retrieves and displays only "the first
set" of records in accordance with the paging
spec
Making a suggestion is difficult without knowing what tools/tiers or
other specifics are involved.

"getParameters" is plural; it returns as many "id"s as it can in an array, even
if there's just the one.

1. encode user id in the order id you store in the db:
user-id 123
relative order-id 41
stored order-id = 123-41
this way he has no chance to request an order from another user ever,
since even he sends 51 to check for order 51 of user 456 the system
will look up for 123-51 instead of 456-51.

No, I mean that I am a user and log in as usual. I can see that my orders have
id's such as 5, 10 and 42. Now I trick a little bit and send another id, say 41
(which is an order of another user), and without a check the action would show
me this order. What's the best way to avoid this situation?
Just to clarify things, do you mean another user sending your
sessionId stored in your cookie to the shop?
