ecside 存在多次执行Action的bug

changkui 2007-04-04

在经典的struts中使用ecside组件，对于存在分页的情况，会多次执行Action。
拿ecside1.3中的demo: 传统Action/servlet方式，当点击该链接时，会发现程序会连续两次执行相应的Action，同时后天会输出以下信息：2007-4-4 13:33:33 org.apache.tomcat.util.http.Parameters processParameters
警告: Parameters: Invalid chunk ignored.
对于单页情况，不存在上述问题！
请作者检查一下该问题！谢谢！

两次是正常的因为会预读取下一页你说的Parameters: Invalid chunk ignored问题我再查一下吧
谢谢提示

我这里也出现了同样的情况
网上搜索没找到什么信息

我这边也有Parameters: Invalid chunk ignored提示

我在页面链接中使用struts的.do方式，通过action类后进入包含ecside标签的列表页，显示为空白页，页面左下方js总是提示edsideutil未定义，查了一下，这是个js变量，在ecside.js里有定义，我已经在页头引入了ecside.js。
而当我按照ecside2.0带的例子那样偷懒，将获得结果集的代码写在页面上时，却可以正确显示页面，这是bug还是不支持这种功能？

另外：即使按照后面的方式获得结果集，翻页功能似乎不起作用，左上角显示正在提交后，页面就一直处于运行状态了，好几分钟后仍然是那样。
在控制台上打印了大概十几个select语句,大致如下：
Hibernate: select tdship0_.PORT_SHIP_SEQ as PORT1_0_, tdship0_.SHIP_ID as SHIP2_0_, ... ... from td_ship tdship0_ where 1=1
所有的sql语句都相同，似乎是死循环

STRUTS版本?
还有能否把JSP页面帖上来看看谢谢

sharong 2007-04-30

程序的架构为struts1.x+spring1.2.9+hibernate3.2.3
如果我在Action类里编写如下代码

public class DemoAction extends DispatchAction {
	private static final Log logger = LogFactory.getLog(DemoAction.class);
	public ActionForward search(ActionMapping mapping, ActionForm form, HttpServletRequest request, 
			HttpServletResponse response) {		

		List list = demoService.getTdShipList();
		
		request.setAttribute("records", list);
		logger.info(DemoAction.class + " readlly to forward the list page ... ");
		
		return mapping.findForward("demolist");
	}
}

那么跳转至demoList.jsp时，显示为空白页，页面左下方js总是提示edsideutil未定义，demoList.jsp的代码和democlassic.jsp基本一致，就是在页面去掉了获得records的java代码，同时，页头显示如下：

<%@ page language="java" contentType="text/html;charset=UTF-8" %>
<%@ taglib uri="/WEB-INF/ecside.tld" prefix="ec" %>

不知道为什么我直接使用<%@ taglib uri="http://www.extremecomponents.org" prefix="ec" %>程序报错，只好改成本地tld文件了，现在都是jsp1.2了吧
而jsp页面中，类似democlassic.jsp那样来获得records集合时，列表页的首页是可以显示的，只是翻页出现等待。

这是我的服务端解释jsp后生成的静态文件的内容：

如果使用eXtremeComponents的标签，即在jsp页头写这个语句<%@ taglib uri="http://www.extremecomponents.org" prefix="ec" %>，出现下面的错误：

在fins的demo程序democlassic.jsp中为什么没有报错？

fins 2007-04-30

第一个问题可能是编码原因
你的页面是GBK
我的ecside.js是UTF-8
你转换一下编码吧

下一版本我会提供多种编码的文件,大家在使用不同编码的时候引入不同的文件就可以了

第2个原因我也不太确定能不能告诉我一下你的应用服务器是什么谢谢
