Arguments

Arguments	Type	Direction	Purpose
MetaClass	BaseClass	In	The MetaClass to create the instance from
Result	RelationalObject	Out	The created instance, null if creation failed

Usage

This activity is used to create new UBIK^® objects during the execution of a workflow. Since it only needs to know the MetaClass to create objects from, it can be used to create regular content objects as well as properties or anything else.

This activity does not automatically save changes. If you want to persist the newly created instance, you need i.e. a subsequent SaveObject activity!
