The items of a dynamic selective list are instances of [[ContentClass]], also known as {{UBIK}} objects. So selecting an a dynamic selective list item is just like selecting a query result item during editing a Guid/link property. In fact, properties having dynamic selective lists are Guid properties and the feature shares the same technology as the general Guid property editing. In other words:* The items are found through a filter query (specificalaly specifically a DSL_QUERY);
* The display strings of the selected item are presented as the display value of the property;
* The UID of the object/item is the actual value of the property;
