javax.faces.FacesException:加载JSF页面时解码资源数据时出错

Question

我在加载JSF页面时遇到了下面提到的错误.页面成功加载,页面上的所需操作也已完成,但是出现此错误.

jsf页面包含选项卡面板,单击每个选项卡面板时出现错误.另外,我发现如果我将页面的某一部分保留为render = false,则错误不会出现,但该部分也不会被重新呈现.

我正在使用JSF2.0和JSP.和RF3.3

jsf页面和组件的代码片段,当在bean中呈现= false时,不会引发上述错误.

<rich:tab ignoreDupResponses="true" id="tabModify"
    style="overflow:auto" styleClass="richTab" label="#{}"
    eventsQueue="queueForTab" actionListener="#{}">
    <rich:layout>
        <rich:layoutPanel position="right" id="pnlmodfy">
            <h:form id="frmModify">
                <h:panelGrid>
                    <h:outputLabel value="#{} * :" escape="false" styleClass="intro" />
                    <h:outputText value=" : " styleClass="intro" />
                    <rich:comboBox id="Mdfy" value="#{Bean.str}"
                        suggestionValues="#{Bean.arraylist}">
                        <a4j:support id="id"
                            actionListener="#{Bean.actionListener}"
                            ajaxSingle="true" event="onchange" reRender="modify">
                        </a4j:support>
                    </rich:comboBox>
                </h:panelGrid>
                <a4j:outputPanel id="modify" ajaxRendered="true">
                    <h:panelGrid columns="3" id="modify">
                        <h:outputText value="Description *" styleClass="intro"/>
                        <h:outputText value=" : " styleClass="intro" />
                        <h:inputTextarea id="Desc" required="true"
                            styleClass="textBox" label="Description"
                            value="#{Bean.strDesc}">
                        </h:inputTextarea>

如果outputPanel绑定到支持bean以进行呈现,并且最初将值设置为false,则不会出现错误.但是在重新呈现outputPanel时,outputPanel永远不会出现.

问题基本上出现在包括组件上.我在页面中有4个选项卡.在两个选项卡上,我使用listshuttle(每个选项卡上有2个组件).在两个选项卡上,源和目标绑定到listshuttle的arraylist是相同的.

是由于这个原因,我将相同的列表绑定到两个班车.然而,另一个选项卡中的相同代码工作绝对正常....

ListShuttle代码: -

<h:outputText value="Select" styleClass="intro" rendered="#{!empty Bean.lstAvailable}"/>
<h:outputText value=" : " styleClass="intro" />
<rich:listShuttle id="listShuttleN" sourceValue="#{Bean.lstAvailable}" targetValue="#{KPIManagement.lstSelected}"  var="items" listsHeight="100" sourceListWidth="100" targetListWidth="100" sourceCaptionLabel="Available" targetCaptionLabel="Selected" rendered="#{!empty Bean.lstAvailable}">       
<rich:column>
<h:outputLabel value="#{items}"></h:outputLabel>
</rich:column>
</rich:listShuttle>

ArrayList代码: -

ArrayList<String> lstAvailable=new ArrayList<String>();

里面有些功能

lstAvailable=class.function(Some variable))
this.setLstAvailable(lstAvailable);

观察到这篇文章的可能答案是我遇到了某种浏览器问题.

当从另一台机器访问相同的应用程序时,绝对没有异常......这很奇怪,因为我使用的是Firefox 11.0而另一台机器有Firefox 4.0

这真的是浏览器的问题吗？

现在,所有Firefox升级> 10.0的问题都出现了问题.在Firefox浏览器脚本中有一些变化,它不允许正确读取树.

请在项目中添加以下内容以消除所有与Firefox浏览器相关的问题: -

import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.net.URLDecoder;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;

public class RichFacesFirefox11Filter implements Filter {

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        chain.doFilter(new HttpServletRequestWrapper((HttpServletRequest) request) {
            @Override
            public String getRequestURI() {
                try {
                    return URLDecoder.decode(super.getRequestURI(), "UTF-8");
                } catch (UnsupportedEncodingException e) {

                    throw new IllegalStateException("Cannot decode request URI.", e);
                }
            }
        }, response);
    }

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        // do nothing
    }

    @Override
    public void destroy() {
        // do nothing
    }

}

请在web.xml文件中输入此过滤器.

<filter>
    <filter-name>RichFacesFirefox11Filter</filter-name>
    <filter-class>Packagename.RichFacesFirefox11Filter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>RichFacesFirefox11Filter</filter-name>
    <url-pattern>/a4j/*</url-pattern>
  </filter-mapping>

这肯定会消除与Firefox浏览器和RichFaces组件相关的所有问题.
