[not at google - send to devlin, 2014/04/02 21:52:14]

the schema compiler will generate all of this for you. you shouldn't need any
manual Value unpacking:

api::automation_internal::PerformAction::Params params(
    api::automation_internal::PerformaAction::Params::Create(args_));

then access params.processId etc.

it will also unpack to the correct enums so GetActionType should be unnecessary.

p.s. people typically will often do "using
api::automation_internal::PerformAction" as well, but up to you.

Done.
