jsf - Primefaces数据表rowEditor

我正在使用Primefaces的p:dataTable显示可编辑的表格。有什么方法可以检测到何时单击了p:rowEditor图标？我需要这样做是因为我想在编辑模式下禁用为行删除添加的p:commandLink。

这是.xhtml:

<p:dataTable paginatorAlwaysVisible="true"
                 paginator="true"
                 paginatorPosition="top"
                 paginatorTemplate="{CurrentPageReport} {PageLinks} {RowsPerPageDropdown}"
                 rowsPerPageTemplate="10,25,50"
                 rows="10"
                 editable="true"
                 value="#{userController.allUsers}"
                 var="user"
                 >
        <p:ajax event="rowEdit" listener="#{userController.onEdit}"/>
        <p:column headerText="First Name">
            <p:cellEditor>
                <f:facet name="output">
                    <h:outputText value="#{user.firstname}"/>
                </f:facet>
                <f:facet name="input">
                    <h:inputText value="#{user.firstname}"/>
                </f:facet>
            </p:cellEditor>
        </p:column>

        //. . . some other data columns

        <p:column headerText="Options">
            <p:rowEditor/> <br/>
            <p:commandLink id="deleteLink" styleClass="ui-icon ui-icon-trash"  action="#{userController.deleteUser(user.userId)}"/>
        </p:column>

在这里，我发现了与Bean有关的部分:

@ManagedBean
@SessionScoped
public class UserController {
    @EJB
    private UserBean userBean;
    @EJB
    private TeamBean teamBean;
    private Integer currentUserId;
    private String newUserUsername;
    private String newUserPassword;
    private User.AccountType newUserAccountType;
    private String newUserFirstName;
    private String newUserLastName;
    private Integer newUserTeamId;

    // ... some create/ update/ delete functions that work

    public void onEdit(RowEditEvent event) {
        try {
            User user = (User) event.getObject();
            System.out.println("Edit: " + user);

            userBean.update(user.getUserId(), user.getUsername(), user.getPassword(),
                User.AccountType.valueOf(user.getAccountType()), user.getFirstname(), user.getLastname(),
                user.getTeam() == null ? null : user.getTeam().getTeamId());
            System.out.println("User " + user.getUserId() + " updated: " + user.getFirstname());
    } catch (InexistentUserException ex) {
        Logger.getLogger(UserController.class.getName()).log(Level.SEVERE, null, ex);
    } catch (InvalidUsernameException ex) {
        Logger.getLogger(UserController.class.getName()).log(Level.SEVERE, null, ex);
    } catch (InexistentTeamException ex) {
        Logger.getLogger(UserController.class.getName()).log(Level.SEVERE, null, ex);
    } catch (DataBaseException ex) {
        Logger.getLogger(UserController.class.getName()).log(Level.SEVERE, null, ex);
    }
}

}

谢谢!

最佳答案

检测何时单击p:rowEditor的事件是:

<p:ajax event="rowEditInit" listener="#{Bean.someListener}" />
