Hi Niklas, my orignal thinking is that we can enhance the API to HookManager::hooksAvailable(const string& hook), but the slave do not know each hook's real function, so we cannot check this in slave. Yes, your explanation does makse sense, thanks! ;-) - Guangya ----------------------------------------------------------- This is an automatically generated e-mail.
