Pessoal,
É realmente necessário que os managedBeans tenhos os métodos
getters e setters ?
O motivo é que no nosso sistema usamos uma classe só pra representar
os dados da vista (ex:modeloVO). Essa classe só possui os atributos da vista
ela é populada automaticamente pelo nosso framework.
A idéia seria ver se é possível substituir nosso framework pelo JSF.
Só que a existência de métodos get e set complicaria a manutenção do sistema.
Sim, todos os atributos da tela precisam ter os getters e os setters. O managed bean representa a tela e o controller junto o que se pode fazer é ter um VO e no teu managed bean ter um atributo desse teu VO. E na página JSF você acessaria assim: #{managedBean.atributoVo.atributo}
Funciona normal, inclusive eu gosto mais dessa abnordagem!
A configuração do faces-config.xml fica assim:
<managed-bean>
<description>Agenda do usuário</description>
<managed-bean-name>agenda</managed-bean-name>
<managed-bean-class>demo.AgendaDB</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
<managed-bean>
<description>Classe de acoes</description>
<managed-bean-name>agendaAction</managed-bean-name>
<managed-bean-class>demo.AgendaAction</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-class>demo.AgendaDB</property-class>
<property-name>vo</property-name>
<value>#{agenda}</value>
</managed-property>
</managed-bean>
O Exadel tá reclamando do managed-property, reclamando da falta
de elementos. Mas já tem o property-class e property-name junto com
o seu valor.
Valeu!
Eu corrigi o problema no faces config.
Mas o que acontece agora é que quando eu faco uma busca. o Bean nao vem
com os valores atribuidos
