Hi guys. I've got a struts application design question for the group.
I've got a webapp which guides the user through creating a large model
object. The process takes several pages - each page has its own form
bean which is used to update the model object (which has no real notion
that it's in

Without reset, you'd never be able to 'un-check' an HTML checkbox.
Sure you would -

So if you have foo=bar you would have nothign if foo was not checked.
If you try it with a GET HTML form you'll see that behavior.
