Flex 4.5.1 运行时 ReferenceError:错误 #1065:变量......未定义 [英] Flex 4.5.1 runtime ReferenceError: Error #1065: Variable ... is not defined

问题描述

好的，我需要一些帮助.我从 Flash Builder 4 升级到 Flash Builder 4.5，并将我的项目切换到 4.5.1 sdk.我使用了一个 ant 脚本来构建我的项目，所以我修改了它以使用适当的 flexTasks.jar、mxmlc 等...

Ok, I need some help on this one. I upgraded from Flash Builder 4 to Flash Builder 4.5 and have switched my project to the 4.5.1 sdk. I use an ant script to build my project, so I modified it to use the appropriate flexTasks.jar, mxmlc, etc...

现在，如果我从一个空白的 bin-debug 文件夹开始，然后构建并运行应用程序，一切正常.但是，如果我随后更改代码并构建(不删除 bin-debug)然后运行该应用程序，则会出现运行时错误:

Now, if I start out with a blank bin-debug folder, then build and run the app everything works fine. However, if I then make a code change and build (without deleting the bin-debug) then run the app I get a runtime error:

ReferenceError: Error #1065: Variable ... is not defined.
at flash.display::MovieClip/nextFrame()
at mx.managers::SystemManager/deferredNextFrame()[E:\dev\4.5.1\frameworks\projects\framework\src\mx\managers\SystemManager.as:284]

at flash.utils::Timer/_timerDispatch()
at flash.utils::Timer/tick()

同样，如果我删除 bin-debug 文件夹并再次编译，它运行没有问题.

Again, if I delete the bin-debug folder and compile again it runs with no problems.

它抱怨的变量始终是指向用作图标的图像文件的类变量.我用来创建 var 的代码:

The variable it complains about is always a Class variable that points to an image file used as an icon. The code I use to create the var:

[Embed(source="/assets/icons/close-32x32.png")] 
public var closeIcon:Class;

该文件存在，我验证了当它给出该错误时，该文件位于 bin-debug/assets/icons 文件夹和 src/assets/icons/文件夹中.

The file exists, and I verified that when it gives that error the file is in the bin-debug/assets/icons folder and the src/assets/icons/ folder.

抛出错误后，如果我点击 Flash Builder 中的继续按钮，它会在下一个指向图像文件的类变量上再次抛出相同的错误.

After the error is thrown, if I hit the continue button in Flash Builder it then throws the same error again on the next Class variable pointing to an image file.

有什么想法吗?删除/重新编译需要几分钟，所以显然这让我发疯.

Any ideas? The delete/recompile takes several minutes, so obviously this is driving me mad.

在调试模式下编译的 Ant 任务:

<target name="compile-debug">
    <echo>Compile MXML</echo>
    <mxmlc 
        file="${SRC_DIR}/${MAIN_SOURCE_FILE}"               
        debug="true"
        optimize="false"
        output="${DEBUG_DIR}/${APP_ROOT_FILE}" 
        append="true"               
        actionscript-file-encoding="UTF-8"              
        keep-generated-actionscript="false"
        link-report="MyReport.xml"
        maxmemory="2048m"
        incremental="true">

        <!-- Get default compiler options. -->
        <load-config filename="${FLEX_HOME}/frameworks/flex-config.xml"/>
        <load-config filename="${FLEX_HOME}/frameworks/air-config.xml"/>

        <!-- List of path elements that form the roots of ActionScript class hierarchies. -->
        <source-path path-element="${FLEX_HOME}/frameworks"/>

        <!-- Include Themes -->
        <!-- NOTE: Spark theme required -->
        <theme dir="${FLEX_HOME}/frameworks/themes/Spark/">
        <include name="spark.css" />
        </theme>
        <theme dir="${FLEX_HOME}/samples/themes/spark_graphite/">
        <include name="spark_graphite.css" />
        </theme>                

        <!-- List of SWC files or directories that contain SWC files. -->
        <compiler.library-path dir="${FLEX_HOME}/frameworks" append="true">
        <include name="libs" />
        <include name="../bundles/{locale}" />                  
        </compiler.library-path>

        <!-- uncomment if you have external libs (swc files) -->    
        <library-path dir="${LIB_DIR}/riaspace/" append="true">
        <include name="*.swc" />
        </library-path> 
        <library-path dir="${LIB_DIR}/AlivePDF/" append="true">
        <include name="*.swc" />
        </library-path>             
        <library-path dir="${LIB_DIR}/coltware/" append="true">
        <include name="*.swc" />
        </library-path>
    </mxmlc>

</target>

其中 FLEX_HOME = /sdks/4.5.1

Where FLEX_HOME = < path to flash builder >/sdks/4.5.1

推荐答案

答案被埋在了Maxim 在上面的评论中引用的帖子:

--> 尝试关闭增量编译.

--> Try turning off incremental compilation.

我在这里使用一个简单的 mimeType='application/octet-stream' 嵌入遇到了同样的问题，在阅读 Maxim 的文本时，这个问题突然出现，因为我最近更改了我的自定义构建工具以使用增量编译:在增量编译期间嵌入有时会失败"

I had the same issue here with a simple mimeType='application/octet-stream' embed, and when reading Maxim's text this jumped out because I'd recently changed my custom build tools to use inremental compilation: "Embed sometimes fails during incremental compilation"

此失败的结果是 .swf 包含如下内容:

The result of this failure is that the .swf contains something like this:

<DefineBinaryData id='1' length='1024' />

看起来是空的，而不是这个(来自工作文件):

which looks like it's empty, instead of this (from the working file):

<DefineBitsLossless2 id='1' encoding='base64'>
(.. in my case, 1024 bytes of base64-encoded data)
</DefineBitsLossless2>

(这为我解决了这个问题，非常感谢 Maxim.我希望它也为你解决了.)

(This solved it for me, so a big thank-you to Maxim. I hope it solves it for you too.)
