Primefaces从2.2.1版到3.4版的变化？

Question

我正在集成在线白板项目，其中的源代码发现here。它最初是为primefaces版本2.2.1编写的，但我们希望与使用最新的primefaces版本3.4的主应用程序集成。在切换到最新版本后，我们得到了很多javascript错误，其中一些错误被粘贴在下面。如果我们必须从2.2.1版升级到3.4版的primefaces，我们需要寻找什么？

错误

Uncaught TypeError: Object [object Object] has no method 'dialog' whiteboard.js.jsf:67
Uncaught ReferenceError: whiteboardDesigner is not defined :8080/emyed-whiteboard/whiteboard/workplace/fc4b4afe-f96f-442b-a0d0-bb29a46836dc/9fb61421-8c0f-4cbb-b0f7-96dc5e31bd56/:73
Resource interpreted as Image but transferred with MIME type text/css: "http://localhost:8080/emyed-whiteboard/javax.faces.resource/whiteboard.css.jsf?ln=css". jquery.js.jsf:14
Uncaught ReferenceError: whiteboardDesigner is not defined :8080/emyed-whiteboard/whiteboard/workplace/fc4b4afe-f96f-442b-a0d0-bb29a46836dc/9fb61421-8c0f-4cbb-b0f7-96dc5e31bd56/:82

根据上述错误，未定义whiteboardDesigner。但是它已经在一个javascript中定义了。

出现错误的Html页面

  <button type="button" title="Draw Free Line" onclick="whiteboardDesigner.switchToMode('freeLineMode', 'pointer')" class="toolboxItem ui-button ui-widget ui-state-default ui-corner-all ui-button-text-icon-primary" value="Draw Free Line">
Uncaught ReferenceError: whiteboardDesigner is not defined

Javascript

// create a global whiteboard designer instance
whiteboardDesigner = new WhiteboardDesigner(new WhiteboardConfig(), whiteboardId, user, pubSubUrl, pubSubTransport);

Answer 1

发现，我们已经在资源目录中包含了jQuery库。采取以下两项措施来解决问题。

1.Since primefaces 3.4 comes with latest version of jQuery library, we have removed the library which we added in the resource dir. This have resolved the issue. 
2. Added jQuery-UI to the resource dir for dialog function to work

除了PrimeFaces blog，PrimeFaces还保留了一个migration guide on their Google code site。

看到你发布的代码，我有点担心。它看起来像Java，而不是JavaScript。(不过我不是JavaScript专家。)
