UBIK® supports defining a list of values for users to choose from instead of letting them enter arbitrary values. These are what we call selective list and selective list items.
Static & dynamic versions
Previously, such a list and list items are static and parts of a MetaProperty, which means it's difficult or even impossible to update once they are configured and delivered to the clients in productive environments.
In some scenarios where such lists or list items are known to change quite often, a more dynamic version is needed.
Technical concept
The items of a dynamic selective list are instances of ContentClass, also known as UBIK® objects. So selecting an 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 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;
- Through this Guid link, it's possible to get all property values on the selected item.
Dynamic items
The crucial part of this new solution is that it's dynamic, meaning the items to choose from can vary upon data changes of the following.
