getNodeSourceTypeIndex cannot get source type index for more than one node

[sdlj2008]

It seems that the code can only return type index for all node or one node, if there are more than one node, for example, if I would like to get the type index for the 1st, 2nd and 3rd node, the code can only return type index for the 1st node, see return value[0].

    if len(argv) == 0:
        return np.array(value)
    else:
        return value[0]

and the parameter j is not used in this function.
