Primefaces 2.2.1, seems do not accept two tables on the same page_问答_开发者

I urge the support of you guys.

I'm using JSF 2.0. Primefaces and 2.2.1.

I need to update a <p:datatable> when a row on another <p:datatable> is selected. Both on the same page.

When a Customer is selected would like to display their respective Parties.

Note: Don't want to work with FetchType.EAGER in my EntityBean.

Following is the code:

clients.xhtml:

ClientMB.java:

@ViewScoped
@ManagedBean
public class ClientMB {

    /**
     * DAOS
     */
    PartDAO interDao = new PartDAO();

    /**
     * BEAN PROPERTIES
     */
    //NOVO CLIENTE
    private Client novo = new Client();

    public Client getNovo() {
        return novo;
    }
    public void setNovo(Client novo) {
        this.novo = novo;
    }

    //CLIENTE SELECIONADO
    private Client selected = new Client();

    public Client getSelected() {
        return selected;
    }
    public void setSelected(Client selected) {
        this.selected = selected;
        this.parties = partDao.list(selecionado);
    }   

    //CLIENTES
    private List<Client> clients;

    public List<Client> getClients() {
        if(clients==null){
            clients = cliDao.list();
        }
        return clients;
    }

    //INTERLOCUTORES
    private List<Part> parties;

    public List<Part> getParties() {
        parties = partDao.list(selecionado);

        return parties;
    }    

    //ACTION HANDLERS...

}

Note: A Client has none, one or more Part ies. When I change <p:datatable> by <h:datatable> everything works normally.

Thank you for any help or example code.

It seems that <p:datatable> instant row selection needs the rowSelectListener attribute and a backing bean listener method in order to work correctly.

Try to put an empty listener method in the backing bean and add the attribute to the table:

<p:dataTable id="clientsTable" var="c" 
             value="#{clientMB.clients}" paginator="true"  
             rows="10" selection="#{clientMB.selected}" 
             selectionMode="single"
             rowSelectListener="#{clientMB.onRowSelect}"
             onRowSelectUpdate="partiesTable">

in the bean:

public void onRowSelect(SelectEvent event) {
    // do something here or not  
}
