the correct way will be to define the generic error handler in the
root controller. in TG2 this will be a lot easier as you can edit your
rootcontroller in your /lib.
in tg1 it's a bit more complicated you will do something like this.
remember they are objects.
class myRootController(RootController):
@expose()
def errorHandler(......)
......
class Controller1(myRootController):
etc.
class Controller2(myRootController):
etc.
that way you have one definition of the error handler and it's
inherited to all of them.
