I'm developing a system using JSF, PrimeFaces, JPA, maven and PostgreSQL. I am new to JEE and am having difficulties with using PrimeFaces, so let's get down to the problem:
I have a client list screen and on this screen I would like to be able to view, update or delete a registered client.
For starters I'm trying to display information from a selected client, however, by selecting the object on the screen and clicking the button to display dialog , I'm getting the following exception:
Can not convert Client {"here is the selected object's information :)"} of type class model.entity.Customer to class javax.faces.model.ListDataModel
ManagedBean :
@ManagedBean
@SessionScoped
public class ControlerCliente implements Serializable {
private static final long serialVersionUID = 1L;
private Cliente cliente;
private Endereco endereco;
private ListDataModel<Cliente> selectClientes =null;
public ControlerCliente() {
this.endereco = new Endereco();
this.cliente = new Cliente();
}
public List<Cliente> obterClientes() {
return ClienteModel.getInstanceCliModel().findAllClientesModel();
}
}
Listing screen:
