    Description copied from interface: IdGenerator
    
    Returns the next desktop ID for the specified desktop, or null to generate the default ID.
    Default (if null is returned): ID is generated randomly. In other words, the desktop's ID, by default, is not deterministic. To have a deterministic value, you have to implement this method.
    Notice that UUID cannot be empty and can only have alphanumeric characters or underscore (i.e., a-z, A-Z, 0-9, and _).
    Also notice that we can retrieve the execution by use of Desktop.getExecution(), or Executions.getCurrent().
    
    Specified by:
    
    nextDesktopId in interface IdGenerator
    
    Returns:
    
    the next desktop ID, or null to generate the default ID.
