Greetings,
I am building a Property Manager Page to allow users to select multiple face. I need to store face id or persistent id of each face through selection box object. While checking selection box object,it return only the array with zero index. Is there any other way to get all face id using the PMP selection box?

Note: Currently we are using a different approach to  store the id through selection manager, but store id not identified the respected entity.

Thanks.
