All Implemented Interfaces:

ChangeEventSource, Model, ModelData, java.io.Serializable

public class BeanModel
extends BaseModel

A ModelData instance that wraps a bean. BeanModels cannot be instantiated directly, rather, they are returned by BeanModelFactory.

Nested beans are supported when creating BeanModel instances with limited support for nested lists of beans. Any child lists must be defined with java.util.List and must be paramertized with a BeanModelTag class or subclass.

When working with bean models, avoid setting beans as values, rather, set the wrapping bean model instance.
