Question

每当我尝试导航时，我的datascroller只会显示前5条记录。我肯定会犯一些愚蠢的错误..

这是我的xhtml文件

        <ui:define name="content"> 
            <h:form>
                <h:panelGrid>
                    <rich:dataScroller for="sampleData" maxPages="20" id="scroller"
                page="#{richBean.scrollerPage}">
                    <rich:dataTable id="sampleData" value="#{richBean.employees}"
                        var="loc" rows="5">
                        <rich:column>
                            <h:outputText value="#{loc.empId}" />
                        </rich:column>
                        <rich:column>
                            <h:outputText value="#{loc.empName}" />
                        </rich:column>
                        <rich:column>
                            <h:outputText value="#{loc.dept}" />
                        </rich:column>
                    </rich:dataTable>
                </h:panelGrid>
            </h:form> 
        </ui:define>
    </ui:composition> 
    </html>

和我的java文件

@ManagedBean(name = "richBean", eager = true)
@SessionScoped
public class JavaBeatRichfacesBean {
    private List<employee> employees;
    private int scrollerPage=1;

public int getScrollerPage() {
    System.out.println("getScrollerPage");
    return scrollerPage;
}

public void setScrollerPage(int scrollerPage) {
    System.out.println("setScrollerPage");
    this.scrollerPage = scrollerPage;
}

    public JavaBeatRichfacesBean() {
        this.employees = new ArrayList<employee>();
        employee employee = null;
        for (int i = 1; i < 50; i++) {
            employee = new employee();
            employee.setEmpId(String.valueOf(i));
            employee.setEmpName("Name : " + i);
            employee.setDept("JSF");
            employees.add(employee);
        }
    }

    public List<employee> getEmployees() {
        System.out.println(employees.size());
        return employees;
    }

    public void setEmployees(List<employee> employees) {
        this.employees = employees;
    }

}

EDITED 我注意到的两件事是

我每次都要刷新以更改页面导航。
如果使用h：dataTable而不是rich：dataTable ..它正在工作
好的，令人惊讶的..
如果我在rich中添加execute =“@ form”render =“@ form”：datatable工作正常但我双击一切..

任何解释为什么这种情况会有用..

rich：dataScroller只显示第一页
