Migrating from version 2015.2.902 to version 2015.3.930 cause splitter not to be generated at all. Also in 2016.1.112 it doesn't work
Code that working well in 2015.2 :
<div kendo-splitter role="main-view" class="main-panels1 1 " k-orientation="horizontal" ng-style="{height:contentHeight(-40)}"
k-panes='[{ collapsible: true, size: "50%" }, { collapsible: true }]' >
