BuiltinActions :: LoadDynamicControl - Load control at runtime
In order to load controls at run-time, this action can be called. The action requires, however, a class and control name, which must be provided in options DYNLOAD_CLASS and DYNLOAD_CONTROL. Thus, the action is typically called from within context functions but not as action via action buttons from the application.
Return value: - internal feature (not documented) ( logical )
