You can get your information back to your application from the client
in two ways:
1. Using Ajax - maybe use DWR or Prototype to call an Action/Manager
and persist the value.
2. Put the value in a hidden field. When you submit the form, you can
grab the value of the hidden field in your Action and do what you need
to with it.
Does that help?
