the input was twice.
ERROR: There is a table connected to input vector map ‘c_ele_basin@g7’, but
there are no categories present in the key column ‘cat’. Consider using
v.to.db to correct this.

v.to.db map=c_ele_basin@g7 option=cat columns=cat
Lese Feature…
Aktualisiere die Datenbank…
Der Datensatz (cat 1) existiert bereits (nichts eingefügt).
1 Kategorien gelesen von der Vektorkarte (Layer 1).
1 Datensätze aus der Tabelle selektiert (Layer 1).
1 Kategorien gelesen von der Vektorkarte existieren in der Selektion der
Tabelle.
0 Datensätze aktualisiert/eingefügt (Layer 1).

v.to.db-output => the category is already in the table, nothing updated.

any ideas?

Could it be related to Ticket #1139?
Anyways I’ve found that v.report has a strange behavior, i.e. the perimeter value calculated sometimes is not correct or is zero (grass 6.5svn on debian). I didn’t report it yet because I wasn’t able to replicate the error again. I see that giohappy has the same problem.
Ideas?

Best,
madi

Helmut
