funeval error with Smolyak basis

[isutoris]

I've noticed that the package has code for Smolyak interpolation, although I'm not sure if it's finished and supposed to be used. Anyway, it doesn't seem to work with funeval:

using BasisMatrices
parms = SmolyakParams(2,3,zeros(2),ones(2))
fspace = Basis(parms)
b = zeros(length(fspace))
x = [0.5, 0.5]
funeval(b, fspace, x)

yields an error:

ERROR: MethodError: Cannot `convert` an object of type Array{Float64,2} to an object of type BasisMatrices.SplineSparse{Float64,Int64,n_chunks,chunk_len} where chunk_len where n_chunks
This may have arisen from a call to the constructor BasisMatrices.SplineSparse{Float64,Int64,n_chunks,chunk_len} where chunk_len where n_chunks(...),
since type constructors fall back to convert methods.

and funeval(b, fspace, x') (i.e. when x is 1 by 2 matrix) results in

ERROR: x must have d=1 columns

The immediate cause seems to be that fspace here is of type Basis{1,...} (since it contains only one set of parameters) and thus the call is dispatched to methods intended for 1D basis structures.
