Thats exactly the problem: It shows nothing. None of my lines has any cat.
That's why you have to run v.category option=add as I indicated in a previous mail.
Another example where it works partly: | Type of Map: vector (level: 2) | Number of points: 1 Number of areas: 56 | Number of lines: 0 Number of islands: 1 | Number of boundaries: 255 Number of faces: 0 | Number of centroids: 56 Number of kernels: 0 | | Map is 3D: No | Number of dblinks: 1 successfully created a table with 57 entries ?->.
What is the problem ?
And now: how to do the same with boundaries?
Why do you want your boundaries to have category values ? An area in GRASS is defined by the combination of boundaries with a centroid and the attribute data is attached to the centroid, not to the boundary.
If you really want cat values for your boundaries, again: use v.category option=add type=boundary.
