Estou verificand…
Alguem tem alguma dica???
Valeu Obrigado

O que este metodo faz?explique melhor e poste o codigo tbm,se possivel.

Bom eu só fiz para teste ma da uma olhada:

<h:commandLink immediate="true" value="Teste" action="#{UsuarioController.cadastrarUsuario}" disabled="#{LoginController.validaUsuarioInserir}"> <f:param id="id_cadastrarUsuario" name="id_recupera" value="11" /> </h:commandLink>

esse é o meu command link que chama essa funcao no caso da tag disabled

public boolean validaUsuarioInserir() {
return false;
}

Consegui… Ele fica esperando um bean… Eu estava chamando uma função… Então oq eu fiz no nome da funcao foi:

public boolean getValidaUsuarioInserir() {  
    return false;  
    }

Agora funcionou…

Vc teria uma forma melhor de fazer isso???
Mesmo assim obrigado e valeu pela ajuda
