Exception during the creation of MailList
See "Error log" for details.

Eric Clayberg wrote:The Mail example has a bug and is poorly designed from an OO point of view to begin with. It throws an NPE at design time (it's not very carefully written), so you need to fix the following NPE (which you should see in your log)...
If you comment out the line Mail.get().displayItem(item); in the MailList class (or add an null check for Mail.get() prior to that line), the Mail class should open in Designer.
