Initializing Array and List Properties

The list-entries element is used to initialize the values of an array or List property. Each individual value of the array or List is initialized using a value or null-value element. Here is an example:

<managed-bean>
    ...
    <managed-property>
        <property-name>books</property-name>
        <list-entries>
            <value-class>java.lang.String</value-class>
            <value>Web Servers for Fun and Profit</value>
            <value>#{myBooks.bookId[3]}</value>
            <null-value/>
        </list-entries>
    </managed-property>
</managed-bean>

This example initializes an array or a List. The type of the corresponding property in the bean determines which data structure is created. The list-entries element defines the list of values in the array or List. The value element specifies a single value in the array or List and can reference a property in another bean. The null-value element will cause the setBooks method to be called with an argument of null. A null property cannot be specified for a property whose data type is a Java primitive, such as int or boolean.
