Hi Romain,
Thanks for the tip; unfortunately it doesn't help: I already based my code on
his, but I had to modify it to be used with dynamic parameters, see below.
Also, it would be good to find out why my code works with faust 1, but is
silent with faust 2 -sch.
Cheers,
Bart.

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
