funeval error with Smolyak basis

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.
