Question

我陷入了非常奇怪的错误。我有一个挂毯页面，我试图导入一个javascript文件。以前，我正在导入extjs-version3.js文件（工作完美），然后我想导入extjs-version4.js文件。因此，我从文件系统中删除了version3文件，将version4文件添加到文件系统，并更改了我的tapestry页面的java代码以导入version4文件。但我总是得到错误，＆＃34;版本3文件不存在＆＃34;！

在调试时，我更改了页面的java代码，以便它现在不导入任何文件。

所以，现在我有一个不导入任何javascript文件的页面，我仍然收到错误，＆＃34;版本3文件不存在＆＃34;。

以下是具体细节。

导入javascript文件的MyPage.java。

@Import(
        library = {
            //"context:js/lib/extjs3/adapter/ext/ext-base-debug.js", 
            //"context:js/lib/extjs3/ext-all-debug-w-comments-v4.js",
            /*"context:js/lib/ext_compat_layer/ext3-compat.js",
            "context:js/lib/ext_compat_layer/ext3-core-compat.js",*/
            //"context:js/page/ActivitiesTab.js",
            //"context:js/lib/extjs3/ux/gridSearch/Ext.ux.grid.Search.js",
            //"context:js/lib/extjs3/ux/gridSearch/Ext.ux.IconMenu.js",
            //"context:js/lib/extjs3/ux/gridSearch/Ext.ux.Toast.js"
        }, 
        stylesheet = {
            /*"context:js/lib/extjs3/resources/css/ext-all.css", 
            "context:js/lib/extjs3/resources/css/xtheme-gray.css",
            "context:js/lib/extjs3/resources/css/theme-gray/core.css",*/
            //"context:js/lib/extjs3/resources/css/icons.css",
            //"context:js/lib/extjs3/resources/css/gridsearch.css"
        }
    )

我收到的错误的堆栈跟踪。

MyPage.tml文件非常简单，没有任何可疑之处，但我可以根据需要发布代码。

为什么tapestry正在尝试加载未包含在任何页面中的js文件？

更新

事实上，无论我在@Import注释中写什么，总是根据前面的代码导入文件。所有页面都会发生这种情况。

Answer 1

这可能是由模板中某些无法加载资产的组件引起的，也可能是由MyPage扩展的父模板引起的。

根据堆栈跟踪，页面net.semandex.salsa.tapestry.pages.ActivitiesTab是问题的原因。 MyPage可能会将其加载到某处。

Answer 2

现在解决了。问题在于我的生产环境而不是Tapestry。当我更改它们时，Eclipse不会更新Java类文件。因此，javascript文件是根据页面的java文件中的先前代码导入的。

Eclipse报告了以下问题。＆＃34;该项目未构建，因为＆＃34;无法删除＆＃39; / someName / bin /＆＃34;。解决问题，然后尝试刷新此项目并构建它，因为它可能不一致＆＃34; 我提到了question并解决了我的问题。

简单的刷新，清理/发布并没有解决我的问题。我不得不关闭Eclipse并重启PC。这修复了我的环境，现在Eclipse正在更新java类。
