> *Cause of the Bug:*
> With some unknown prior actions on the cluster on host page load,
> [code|https://git-wip-us.apache.org/repos/asf/ambari/repo?p=ambari.git;a=blob;f=ambari-web/app/views/main/host.js;h=8a4d01e1548e4f29b601f2cafc827f7588e92896;hb=HEAD#l101]
> returns one of it's elements as plain ember object with no property set (not
> even iColumn key). This breaks the [code|

> ahead. Over here in one of the iteration we are trying to find an element in
> childviews array whose *column* value is undefined. There are many such
> elements in childviews array. So it picks up the first element
> {{App.HostTableMenuView}} and schedules to call showClearFilter function
> later because of Ember.run.next loop. When the run queue is dequeued to
> execute this callback methods, the very first callback method
> "showClearFilter function for App.HostTableMenuView class" fails with Js
> error and other pending callback methods are not executed nor flushed by
> Ember.
> When the next time ember.run.next is executed in the code (normally this
> happens by routing to other page), stale callbacks with no data binding is
> invoked and again leads to JS error at
