TypeError: this.range is null

[murdav]

Dear All,

I was checking it.
But i got this error running the example wmst.html
TypeError: this.range is null

In my custom OL.js 2.13.1 I included:

OpenLayers/Control/TimeManager.js
OpenLayers/TimeAgent.js
OpenLayers/TimeAgent/WMS.js
OpenLayers/Control/DimensionManager.js

Thanks!
