Yes, when repeater instantiates components, it creates a array of ids for each specific id, so each mySlider has an id mySlider[n] where n is the index of the item.
The cleanest way to deal with this is to create a custom component containing all the components and repeat that component. Pass in a reference to the entire currentItem into a typed setter function. You will find that doing this simplifies repeater work immensely, especially when you need to dispatch an event and access the dataProvider item in the handler. You will not need getRepeaterItem().

I'm just trying to create labels that always shows the value of the respective slider. Since this is in a repeater, is it a conflict with the way I assign id to the slider?
