Class: OpenWFE::FieldWfidGenerator

This wfid generator returns as wfid the value found in a given field of the launchitem (if any).

If there is no launchitem or no field, a Kotoba wfid is returned.

This generator is useful for engines that have to use workflow instance ids generated by other systems.
