Sliders does not work with arrays

[korsbo]

slider([1.,2.,3.])

does not work for me in Juno. I think that the immediate culprit is:

InteractNext.jl/src/widgets.jl

Line 97 in 50ac81a

extra_vbinds["data"] = "vals"=>WebIO.jsexpr(svals)

where WebIO should be JSExpr. But when I changed this, I get new errors when I actually use the slider:

MethodError: Cannot `convert` an object of type String to an object of type Float64
This may have arisen from a call to the constructor Float64(...),
since type constructors fall back to convert methods.
