      Hi Monis,

      there is small correction needed in Transactional Form Handler question. Transaction begins in beforeSet and ends in afterSet. Please correct.

      thanks

        Hi Vishal,

        In TransactionalFormHandler, transaction begins in beforeGet() and afterGet() methods. The answer written above is correct.
        Please have a look at the ATG documentation HERE: https://docs.oracle.com/cd/E24152_01/Platform.10-1/ATGPlatformProgGuide/html/s0602subclassingatgformhandlers01.html

        According to the documentation "The transaction management occurs in the beforeGet and afterGet methods. This establishes the transaction before any of properties are set or handler methods are called, rather than in the handler methods themselves"
