Dear all,

can anybody explain the use of the QgsFeature's changeAttribute() function?
this is my code:

newFeature = QgsFeature()
newGeom = #some geometry-creating function here
newFeature.setGeometry( newGeom )
myLayer.addFeatures( [ newFeature ] )
myLayer.setModified()
newValue = "a string"
myIdx = myLayer.fieldNameIndex( 'myfield' )
newFeature.changeAttribute( myIdx, newValue )
   #does not change the field value to new value :-(

what is the second argument of changeAttribute supposed to be?

regards

Bernhard
