From 1de8ae4c3303d16b4a0ee1d11db4f27e00cb9d29 Mon Sep 17 00:00:00 2001
From: Denis Flaven <denis.flaven@combodo.com>
Date: Sun, 16 May 2010 16:47:16 +0000
Subject: [PATCH] - Added validation of the fields based on a regexp pattern -
 Fields that depend on another field (in the same form) get refreshed when one
 of the fields they depend on is changed - Updated the wizard to group all the
 mandatory fields on the first page, since having inter-dependent fields on
 one page is now supported
