在让我的 ember 路由正常工作时遇到了一些麻烦，如果我做得对，我会有点困惑。似乎这部分有很多变化，这可能有点令人困惑。我希望有人能帮我看看这里出了什么问题。
应用
refset.sparklingideas.co.uk:8000
环境
2013 年 11 月 20 日克隆的 Ember App Kit
Ember : 1.2.0-beta.4
Ember Data : 1.0.0-beta.2
Handlebars : 1.1.2
Query : 1.9.1
Node : v0.10.21
Chrome : 31.0.1650.16 beta
OS X : Maverick

抱歉，还没有成功托管它，但我确实有截图来说明：http:

问题
我当前的配置有两个问题。
当单击链接返回到主屏幕（/，“refsets”）时，子屏幕（/：publicid）的内容会被添加到主屏幕的底部。当您来回导航时，这会不断堆积。
单击“显示规则”或“显示概念”按钮的链接时，屏幕变为空白，并且 ember 返回此神秘错误（还提供了其他自定义和 ember 日志记录详细信息）：
Loading concepts in router ember.js:3227 GETing concepts for: {...} ember.js:3227 Rendering refset.concepts with default view <appkit@view:default::ember404> Object {fullName: "view:refset.concepts"} ember.js:3227 Transitioned into 'refset.concepts' ember.js:3227 Uncaught TypeError: Cannot read property 'parentNode' of null ember.js:24102 Assertion failed: Emptying a view in the inBuffer state is not allowed and should not happen under normal circumstances. Most likely there is a bug in your application. This may be due to excessive property change notifications. ember.js:3227 Uncaught Error: You cannot modify child views while in the inBuffer state ember.js:22892
这些有问题的“链接到”语句位于：
- 在“模板/refset.hbs”（面包屑，顶部）中：导致内容堆叠
- 在 'template/refset/concept.hbs' 和 'template/refset/plan.hbs'(heading, top): 导致 ember 错误
来源可以在上面的链接中找到，也可以在下面复制。
