From 3f782a1454664a5f8c4f76fab1af1e0bb87b96bd Mon Sep 17 00:00:00 2001 From: anishmangal2002 Date: Mon, 14 Jun 2010 02:21:23 +0000 Subject: [PATCH] Add ErrorAlert inherited from Alert Adds the ErrorAlert class which is an alert inherited from the base Alert class. This is very similar to the ConfirmationAlert class with the difference being that it only displays an 'Ok' button in the Alert popup.
