I use ST2.0 - RC. And my problem is the config "tpl" don't work in dataview. This is my code for test :
xtype:'dataview', style:'border:1px dotted yellow', data: [
{name: 'Jamie', age: 100}, {name: 'Rob', age: 21}, {name: 'Tommy', age: 24}, {name: 'Jacky', age: 24}, {name: 'Ed', age: 26} ],
height:"400px", tpl: ['test'],
The result in chrome is empty, and in the inspector I have this :

HTML Code:
<div id="ext-component-3" class="x-dataview-container">
<div class="x-dataview-item" id="ext-element-15"><div></div></div>
<div class="x-dataview-item" id="ext-element-16"><div></div></div>
<div class="x-dataview-item" id="ext-element-17"><div></div></div>
<div class="x-dataview-item" id="ext-element-18"><div></div></div>
<div class="x-dataview-item" id="ext-element-19"><div></div></div>
Have you ideas ?
