-
We want to show the user ALL of the errors they made on the form in one go rather than showing them only the first error.
-
We want to give the user back the data they entered so they can see their own mistake, or to reduce the typing they have to do to correct it.
-
When we send the user back to the list, we want to return them to the same page with the same sort order and search criteria.
-
In the case of a login form, we want the completion of login to send the user wherever they were intending to go before they were interrupted to present their credentials.
