Cannot switch from steps array to regular steps with ticks values

[gaelollivier]

Steps to reproduce

1. Instantiate a slider with a stepsArray
2. Update the slider options to instead use regular steps with showTicksValues set to true

Demo: http://jsfiddle.net/3jjye1cL/135/

Expected behaviour

The slider should update to the new settings

Actual behaviour

TypeError: Cannot read property '0' of null, slider is broken

Good catch! ;) Do you want to submit a PR for this or can you wait for me to fix it?

Actually, these lines:

if (this.options.getLegend) {
   this.getLegend = this.options.getLegend;
}

should be replaced by:

this.getLegend = this.options.getLegend;

At least, for the current error, I don't know yet if toggling stepsArray at runtime can have other impacts.

I'm just prototyping the use of this slider for an app so I won't PR right now. If we decide to use it I'll fix the bug if you didn't do it already :)

[ValentinH]

OK, so can you just try the fix I suggested to see if it does the job?

[gaelollivier]

Yep, just did and it fixes the bug for my use case, thanks ! It doesn't break the tests neither
