Question

我试图构建一个包含openfaces数据表组件的非常简单的页面。

我试图为它启用分页。我已完成指令，就像它的

一样

开发人员指南，但是当我在我的后台bean中获得这两个变量时，pageStart是

总是零！

这是我的.xhtml文件

                </div>
    </h:body>
</html>

这是我的背豆：

package backbeans;

import java.util.List;

import javax.ejb.EJB;

import order.TblBaseCities;
import order.TblBaseCitiesFacadeLocal;

import org.openfaces.util.Faces;

public class TestBean {

    @EJB
    TblBaseCitiesFacadeLocal cities;

    public List<TblBaseCities> getLazyModel(){
        int pageStart = Faces.var("pageStart", Integer.class);
        return cities.findAll(pageStart,Faces.var("pageSize",Integer.class));
    }

    public int getCount(){
        return cities.findAll().size();
    }

    public TblBaseCities getRowByKey() {
        Integer key = Faces.var("rowKey", Integer.class);
        return cities.findById(key);
    }
}

我正在使用openfaces 3.0，myfaces 2.0.4和weblogic 10.3.3服务器

提前致谢

您似乎忘记了自己放置DataTablePaginator组件。您应该将它放在“上方”和/或“下方”方面。只需确保明确指定paginator的id才能使其正常运行。

<o:dataTable ...>
  <f:facet name="above">
    <o:dataTablePaginator id="paginator"/>
  </f:facet>
  ...
</o:dataTable>
