Hi Matteo,
yes because arming the branch_route will be on for all branches of the
transaction - so the branch_route() will be triggered even for the
branch you create in the failure_route -> one PAI in failure route and
one in branch route.
So, you can remove the PAI manipulation from the failure_route() and let
only branch_route to do the job.
Regards,
Bogdan
