未捕获的TypeError：无法读取属性＆＃39; liferay-form＆＃39;未定义的

时间：2014-12-12 10:06:20

标签： liferay liferay-6 spring-portlet-mvc

我在Spring MVC中有一个Web应用程序，并希望将此Web应用程序用作Liferay中的portlet。我创建了portlet控制器类，设置了web.xml, portlet.xml, liferay-portlet.xml和其他文件。当我向Liferay添加portlet时，我在浏览器控制台中收到错误：

Uncaught TypeError: Cannot read property 'liferay-form' of undefined
<{1>}文件中的

我将Liferay 6.2与Tomcat一起使用，并没有注意到服务器日志文件中的任何错误。

我不知道如何找到问题的位置，并且不知道barebone.jsp文件是什么。

2 个答案:

答案 0 :(得分：1)

从第一眼看，您的网络应用程序的javascript与Liferay的浏览器有冲突。正如您所看到的，浏览器会抱怨＆＃39; Uncaught TypeError：无法读取未定义＆＃39;的属性＆＃39; liferay-form＆＃39; 。这意味着只要在页面上添加portlet，它就会搞砸Liferay的javascript。我会尝试从jsp中删除对所有js文件的引用，并逐个添加它们以查看哪个有冲突，然后解决它们。

JFYI，liferay-form可以从其中一个地方引用：https://github.com/liferay/liferay-portal/search?utf8=%E2%9C%93&q=liferay-form，但你无法从这些地方找出罪魁祸首。我的猜测是＆＃39; end.jsp＆＃39;，但我不确定。

答案 1 :(得分：0)

首先，我会检查所有必需的portlet依赖项，例如使用liferay taglib所需的依赖项：

 <dependency>
       <groupId>com.liferay.portal</groupId>
       <artifactId>util-taglib</artifactId>
       <version>${liferay.version}</version>
       <scope>provided</scope>
 </dependency>

另一方面，确保您的portlet解剖结构与官方网站中的一个提供者相同：

https://www.liferay.com/documentation/liferay-portal/6.1/development/-/ai/liferay-plugin-types-to-develop-with-maven https://www.liferay.com/documentation/liferay-portal/6.1/development/-/ai/anatomy-of-a-portl-4

例如，您还没有提到过liferay-display.xml如果这不能解决您的问题，请提供您的portlet源（配置文件和jsp文件抛出错误就足够了）
