Hi Simon,

I agree that support for improved checkbox handling needs to be incorporated
into struts. However the approach you have suggested below does have a
flaw - namely that if you try to implement a multi-part form (ie wizard)
using this approach, some extra care is required to ensure that only the
current page's checkboxes are reset.
There have however been several submissions from myself and others that take
a variety of different approaches to the checkbox problem, so hopefully
we'll see something included soon.
