Rhino预编译工具栏失败，出现1.0.0 - _triageMustache缺失

Question

我们正在构建一个Ember/Java应用程序，并且在maven构建过程中使用Rhino预编译我们的工具栏模板。直到今天，我们还在使用车把RC3和Ember RC3，生活是美好的。今天，我们尝试更新到Ember RC6和Handlebar 1.0.0，现在我们的Rhino预编译器给出了如下内容：

js: "src/main/js/third-party/handlebars-1.0.0.js", line 2024: uncaught JavaScript runtime     
 exception: TypeError: Cannot call method "replace" of undefined
at src/main/js/third-party/handlebars-1.0.0.js:2024

我们已经尝试了我们自己的Rhino编译器和这里找到的一种：https://github.com/locnguyen/ember-rhino-precompiler。

更新

在深入研究一下车把之后，似乎车把-1.0.0产生了与车把RC3略有不同的操作码，特别是缺少了对_triageMustache助手的调用。对于这个车把碎片：

{{#if enableLinks}}<a href="/foo?userId={{unbound loginAsAdminId}}&userAsId={{unbound legacyUserId}}" id="logoutAsLink">Return to {{loginAsAdminName}}</a>{{/if}}

通过RC3，我们可以得到以下内容：

in compile appendContent "<a href="/userportal/returnToAdmin?userId="
getContext 0
pushStringParam "loginAsAdminId" "ID"
pushProgram
pushProgram
emptyHash
invokeKnownHelper 1 "unbound"
appendEscaped
appendContent "&userAsId="
getContext 0
pushStringParam "legacyUserId" "ID"
pushProgram
pushProgram
emptyHash
invokeKnownHelper 1 "unbound"
appendEscaped
appendContent "" id="logoutAsLink">Return to "
getContext 0
pushStringParam "loginAsAdminName" "ID"
pushProgram
pushProgram
emptyHash
invokeKnownHelper 1 "_triageMustache"
appendEscaped
appendContent "</a>"

在1.0.0中，我们得到如下信息：

in compile appendContent "<a href="/userportal/returnToAdmin?userId="
getContext 0
pushStringParam "loginAsAdminId" "ID"
pushProgram
pushProgram
emptyHash
invokeKnownHelper 1 "unbound"
appendEscaped
appendContent "&userAsId="
getContext 0
pushStringParam "legacyUserId" "ID"
pushProgram
pushProgram
emptyHash
invokeKnownHelper 1 "unbound"
appendEscaped
appendContent "" id="logoutAsLink">Return to "
getContext 0
pushStringParam "loginAsAdminName" "ID"
pushProgram
pushProgram
emptyHash
invokeHelper 1
appendEscaped
appendContent "</a>"

注意，对invokeHelper的最后一次调用缺少了助手名。事情就在那里开始恶化。我还不太清楚车把为什么会漏掉这个。

在这里回答我自己的问题:很明显，Ember RC6与工具栏1.0.0不兼容。查看这个线程(我知道它引用了RC5，但问题仍然存在于RC6中)：http://discuss.emberjs.com/t/ember-rc-5-is-not-working-properly-with-handlebars-1-0-0/1391
