public class D2WQueryUnavailable

extends QueryComponent

The D2WQueryUnavailable class is a property-level component that displays a message stating that a query cannot be built based on this property.

One common usage is to indicate that queries have been disabled (for efficiency or correctness) on attributes represented by NSData.

Property-level components are not accessed programmatically. Instead, you use the Web Assistant or Rule Editor to choose the property-level component that Direct to Web uses to display a property on a particular entity and task page.
