Dear Moritz,

thanks for your e-mail.

Choosing the delete option still shows me the boundary of the deleted feature within the map display.

That's the statement I was using:
v.edit map=geb_emiss_KP@PERMANENT type=point,line,boundary,centroid tool=delete where=ID='Geb059811' snap=no

Is this just a display error? (using v.info doesn't give any more attribute data for this object)

No, assuming that you are trying to delete a polygon I guess what happens is that it deletes the centroid (to which the attribute is attached, i.e. which carries the category for this attribute), but not the boundaries of the polygon as they have no attributes attached to them.

I guess that v.edit should have an 'area' type as well (cc'ing to -dev list for that), so that it deletes both the centroid and the boundary when that type is selected... Maybe you could file a wish on the GRASS bug tracker.

For now, you could probably use v.extract with the -r flag, i.e.:

v.extract -r in=geb_emiss_KP@PERMANENT out=NewMapName where="ID='Geb059811'"

(also note the quoted where clause...normally safer).
