view jsf-2

View java.io.NotSerializableException:javax.faces.component.html.HtmlForm,view,jsf-2,managed-bean,View,Jsf 2,Managed Bean,我为bean类使用了视图范围。当我运行应用程序时，出现了错误（JSF2.0，Richfaces3.3.3）如果使用会话作用域，则以下代码可以正常工作 sample.jsp <f:view> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> </head> &l

我为bean类使用了视图范围。当我运行应用程序时，出现了错误（JSF2.0，Richfaces3.3.3）

如果使用会话作用域，则以下代码可以正常工作

sample.jsp

<f:view>
   <html>
      <head>
          <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
      </head>
      <body>
         <h:form id="sampleForm" binding="#{Sample.initForm}">
            <h:outputText value="This is sample form"/>
        </h:form>
    </body>
</html>  
</f:view>

执行此代码后，我得到以下错误

帮帮我。。提前谢谢

事实并非如此。您有两种选择：

只是根本不要将表单组件绑定到视图范围的bean。对于您认为绑定表单组件是正确的解决方案的功能需求，肯定还有其他方法可以实现

将属性

设置为瞬态
private transient HtmlForm initForm;   

这样，在（反）序列化时将跳过该属性

谢谢你的回复。我对所有托管bean类使用了“transient”类型。尽管我得到了相同的错误。要么代码没有重建，要么错误实际上不一样（例如，涉及不同的类）。谢谢你的回复。我对所有托管bean类使用了“transient”类型。尽管我得到了相同的错误。要么代码没有重建，要么错误实际上不一样（例如，涉及不同的类）。
