Wikibooks:Dialog/do/test/rollback

This page tests rollback, in which an action request is retracted to restore the page display from which the request was issued. The first several tests exercise primarily different contexts of rollback; later tests exercise particular causes of rollback. Some causes of rollback (such as failure to parse the page to be viewed) are listed but not supported here because they can't be induced under ordinary circumstances.

To initialize the observables &mdash; which should then be restored by each rollback test &mdash; use to provide incoming values for the second set of parameters, and manually enter new values into the text boxes. (The button doesn't preserve the contents of the text boxes.)
