openfaces数据表问题
我尝试构建一个非常简单的页面，其中包含 openfaces 数据表组件。
我尝试为其启用分页。我已经按照开发人员指南完成了指令
，但是当我在后台 bean 中获取这两个变量时，pageStart
始终为零！
这是我的 .xhtml 文件

，这是我的 back bean：
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
i have tried to build a very simple page that includes openfaces datatable component.
i have tried to enable pagination for it. i have done the instruction just like its
developer's guide, but when i get these two variables in my back bean, the pageStart is
always is zero!
this is my .xhtml file

and this is my back bean:

import org.openfaces.util.Faces;
public class TestBean {

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);
}
}
i am using openfaces 3.0, myfaces 2.0.4 and weblogic 10.3.3 server

您似乎忘记放置 DataTablePaginator 组件本身。您应该将其放置在“上方”和/或“下方”方面。只需确保显式指定分页器的 id 即可使其正常运行。
It seems that you have forgot to place the DataTablePaginator component itself. You should place it in "above" and/or "below" facet. Just make sure that paginator's id is specified explicitly for it to function properly.
