Method Detail

asSelectItems

public static List<javax.faces.model.SelectItem> asSelectItems(List<? extends Persistable> persistables,
                                                               String labelProperty)

Creates items of type SelectItem from the supplied List of persistables, using reflection.
The code of the SelectItem is the Persistable itself and the label is fetched from the Persistable, using the supplied labelProperty.

Parameters:

persistables - The Persistables to convert to SelectItems.

labelProperty - The name of the Persistable's property to be used as the label of the SelectItem.
Reflection is used to invoke the accompanying method. When the property is not found, this is logged as a sever message and the primary key of the persistable is used as the label for the SelectItems.

Returns:

The supplied persistables are returned as items of type SelectItem.
The returned collection may be empty but is never null.
