Lister

To build a dynamic list, generate a list definition block. The background scheduler (lister) wakes up every sixty seconds to search for obsolete lists and uses list definition blocks to generate new lists, which are then stored in the list repository.

Once lister has built a list on the server, multiple clients can request and share the same list without each client having to build its own copy. This method of building lists improves system speed and helps server-side performance.

Note: Lister variables can be defined for scalar type fields only and not for array fields.
