I am testing Zimbra 7.2 before upgrading from 7.1.3 GA 3346. When I deploy current working Zimlets used on our 7.1.3 deployment to the new 7.2 GA 2669 server I receive the following error.:

An error has occurred while initializing the zimlet "xxx". Please notify administrator.

Under show details I see:

TypeError: Object # has no method 'init'


Does anyone know what this is and or what I need to look at to fix it?
