26 | * Annotation used to <em>define</em> new managed beans, including limited/lightweight | |
27 | * initialization. For complex initialiation, the XML specification is necessary. | |
28 | * <p> | |
29 | * One of the advantages is that, on the XML side, it is always necessary to provide complete class | |
30 | * names; here on the Java/annotation side, we can leverage imports. | |
31 | * <p> | |
32 | * The managed bean will have a name that matches the property name; this allows such a bean to be | |
33 | * referenced via the "bean:" binding prefix, or via | |
34 | * {@link org.apache.tapestry.IComponent#getBeans()}. | |
35 | * <p> | |
36 | * This annotation adds a new {@link org.apache.tapestry.spec.IBeanSpecification} to the | |
37 | * {@link org.apache.tapestry.spec.IComponentSpecification}. | |
