BUG: Solved "TypeError: Cannot read property 'length' of undefined" e…

[JohnEricson]

Solves "TypeError: Cannot read property 'length' of undefined" error when using slider connected to datasource in CDE dashboard. The cause of the problem is that sliderData.resultset.length is executed before sliderData = values, resulting in the slider failing to render on start of the dashboard.

Complete error:

My bad! This doesn't really solve the problem. Now it uses the hardcoded minRange, maxRange in properties instead of taking them from the datasource query.

[JohnEricson]

Now I've fixed so the solution works with datasource queries as earlier. I would like this fix to be pulled into master.
