public class NotEmptyChooserPropertyDescriptor
extends atg.repository.ChooserPropertyDescriptor

A property descriptor to be used with a Repository that returns the first object that is not empty or the merged collection of all non-empty values. The getPropertyValue method iterates over the list of property names and fetches the value. If the attribute value merge is set to true (default false) and if the value is not empty, then it is added to a merged collection. If no merging is supposed to occur then we just return the first non-empty value. If all the values are empty, then null is returned.

The term empty means the following:

1. Collection.isEmpty()
2. Map.isEmpty()
3. If an object array length not equal to 0
4. If the object is null
