Unwanted model rounding on options change

[mattesCZ]

I'm trying to switch between two sliders - first is with default precision (0) and step (1), second has precision: 1 and step: 0.1. The default value of model for second slider is 0.4.
While switching from first slider definition to second, everything updates fine, only the default value of model is rounded with precision of the first slider. For 0.4, it rounds it to 0.
I've found out that the watch expression of rzSliderModel is evaluated before the new options - rzSliderOptions and the function thrLow updates the value of model to 0.

Is there a way to force options to be updated before the slider value?

It can be simply fixed like this:

this.scope.$watch('rzSliderModel', function(newValue, oldValue) {
  if (newValue === oldValue)
    return;
  self.applyOptions();  // added applyOptions()
  thrLow();
});

But it is probably not the best way. It calls applyOptions on every model change.

Any ideas to make it better?

Indeed this is a bad behaviour. I reproduced your example here: http://jsfiddle.net/fdkgmbq2/ .

I'm taking a look at the best way to fix this.

I fixed it by simply defining the watch on options before the one on model. Then the order of calls is correct... :D I hope this behaviour won't change later.

Great, thanks.
