This method is called once after all form handler processing is completed. It implements the following transactional steps:
Commit or roll back any transaction that was created in the
beforeSetmethod.If the transaction was already in place before the
beforeSetmethod was called, theafterSetmethod does not end the transaction automatically; this is the application’s responsibility.If a transaction lock was acquired in the
beforeSetmethod, release the lock.
If you’re extending an Oracle ATG Web Commerce form handler and your code makes its own decisions about errors, you can mark a transaction for rollback by calling the setTransactionToRollbackOnly method.
