  • How to pass user-supplied value to a popup?

    Hey guys. I'm relatively new to Spring, so hopefully this will be an easy question. Basically, I have a web application with a form where the user will provide a user ID, then click a button which will look up the provided user ID, then present a popup window with the user's full name (retrieved from a database).

    My question is, how can I get this dynamically-supplied user ID passed to the popup window so the popup window's controller can pull it out of the command object and do the lookup?

    If it makes a difference, I'm using Velocity for my view layer.

    Any hints or suggestions would be greatly appreciated! Thanks!
