Silent errors in ember components
<p>Recently i have found strange behaviour in my application</p>

<p>if i have a problem in component, i don't receive any errors, application loads with blank screen and after several tens seconds i receive a deprecation:
<code>[deprecation id: ember-views.render-double-modify]</code>
without any clues what is the real problem</p>

<p>it might happen when i pass non existing closure action to component,
or event if i manually throw error in computed property in component</p>

<p>it happens in all recent versions of Ember (2.4.6+)</p>

<p>I can not reproduce such behaviour in empty application, so probably problem in my application or addons, but i have no idea how to find what catches errors. </p>

<p>Any ideas how to find source of the problem?</p>
