36  * Abstract implementation of a {@link com.sslexplorer.core.actions.AuthenticatedDispatchAction}
37  * to be used by actions that exist in a popup window instead of the main interface.
38  * <p>
39  * Its primary use is to catch all exceptions and turn them into
40  * {@link com.sslexplorer.core.PopupException}. This is then detected by
41  * the globa error handler which makes sure a different error page is
42  * loaded more suitable for the <i>Popup</i> window it is in.
