How to read full separated column from HDF5 data (array)

I can read part fo array saved in HDF5 file. Is ok , nice!

julia> data = h5read("X.h5", "grupa", (1:3,1))
3x1 Array{Float64,2}:
0.269948
0.561731
0.894856

But I cant read all first column (:,1) :

julia> data = h5read("X.h5", "grupa", (:,1))
ERROR: no method h5read(ASCIIString, ASCIIString, (Colon,Int64))

How to read this column ?
