wxGUI digitizer: error when adding a new column

[mlennert]

• In wxGUI Display Manager, chose Digitize -> New map
• Try to add a new column to the new map:

ATTENTION: Unable to open vector map <test1@user1> on level 2. Try to
           rebuild vector topology with v.build.

A bit more info:

• the column actually gets created
• I can reproduce this with any existing map by just putting it into editing mode and then trying to add a column

I think v.support doesn't need to open the vector on level 2. Changing it to level 1 solves this issue. Any opinion on that?

I don't see any reason why v.support would need topology.

[annakrat]

If there are no objections, I will commit it tomorrow. I just want to avoid breaking v.support because of my insufficient knowledge of vector library...

Done in r64603 and r64604. Moritz, please confirm that it fixed the issue and close this, thanks.

Yes, this fixes it for me. And rapid tests of v.support have not shown any bad consequences. Closing.

Thanks a lot !
