    <p>I'm trying to dynamically switch between layouts in Ember.js by having one outlet named layout in ApplicationView, and several layout classes with an unnamed outlet inside of it. See this JSfiddle: <a href="http://jsfiddle.net/ElteHupkes/SFC7R/2/" rel="nofollow noreferrer">http://jsfiddle.net/ElteHupkes/SFC7R/2/</a>.</p> <p>This works fine the first time, however upon toggling the layout the content disappears. This seems to be the same problem that occurs when you simply re-render the application view (<code>router.get('applicationView').rerender()</code>), making this question somewhat related to my other one earlier: <a href="https://stackoverflow.com/questions/13009470/re-rendering-applicationview-with-outlet">Re-rendering ApplicationView with outlet</a>.</p> <p>I would say that as the controller bindings stay the same, the unnamed outlet should still be connected and the inner view contents should thus be rendered. I'm hoping someone can enlighten me as to why they aren't :).</p> <p>HTML:</p> <pre><code>&lt;script type="text/x-handlebars" data-template-name="application"&gt; {{outlet layout}} &lt;a href="#" {{action doToggleLayout}}&gt;Toggle layout&lt;/a&gt; &lt;/script&gt; &lt;script type="text/x-handlebars" data-template-name="layout1"&gt; &lt;h1&gt;Layout 1&lt;/h1&gt; {{outlet}} &lt;/script&gt; &lt;script type="text/x-handlebars" data-template-name="layout2"&gt; &lt;h1&gt;Layout 2&lt;/h1&gt; {{outlet}} &lt;/script&gt; &lt;script type="text/x-handlebars" data-template-name="index"&gt; Page contents. &lt;/script&gt; </code></pre> <p>JS:</p> <pre><code>App = Ember.Application.create({ autoinit: false, Router: Ember.Router.extend({ root: Em.Route.extend({ index: Em.Route.extend({ route: '/', connectOutlets: function(router) { // Fire toggle once as an initializer router.send('doToggleLayout'); router.get('applicationController').connectOutlet('index'); } }), doToggleLayout: function(router) { this.set('layoutClass', this.get('layoutClass') == App.Layout2View ? App.Layout1View : App.Layout2View); router.get('applicationController').connectOutlet({ viewClass: this.get('layoutClass'), outletName: 'layout' }); } }) }), ApplicationView: Em.View.extend({ templateName: 'application' }), ApplicationController: Em.Controller.extend({}) }); App.IndexView = Em.View.extend({ templateName: 'index' }); App.Layout1View = Em.View.extend({ templateName: 'layout1' }); App.Layout2View = Em.View.extend({ templateName: 'layout2' }); App.set('layoutClass', App.Layout2View); App.initialize(); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
