> what is the second argument of changeAttribute supposed to be?

>From my 'homemade' plugin:

      self.lay_stradearchi.changeAttributeValue (self.minFeature.id(),

self.lay_stradearchi.dataProvider().fieldNameIndex("FIELDNAME"),
                        self.dlgEdit.ui.newCode.text())

First argument is the FEATURE ID,
second argument is the index of the field,
third is the new value.

HTH.
