Many thanks for your reply, Carson.

Yes, I try to use vLayer.commitChanges() and vLayer.updateFeatureCount(),
but this take no effect. Code is:

lstFeatures = []
lstLayers = []
self.layermap = QgsMapLayerRegistry.instance().mapLayers()
for (name, layer) in self.layermap.iteritems():
	lstLayers.append(name)
vLayer = self.layermap[lstLayers[0]]
# for debug: show feature count before adding
#QMessageBox.information(self.iface.getMainWindow(), "Debug", str(vLayer.featureCount()))
provider = vLayer.getDataProvider()
provider.reset()
ft = QgsFeature()
geom = QgsGeometry.fromPloygon([lstCoord])
ft.setGeometry(geom)
lstFeatures.append(ft)
# commit changes
provider.addFeatures(lstFeatures)
self.iface.getMapCanvas.refresh()
#vLayer.commitChanges()
vLayer.updateFeatureCount()
# for debug: show feature count after adding
#QMessageBox.information(self.iface.getMainWindow(), "Debug", str(vLayer.featureCount()))

>From http://spatialserver.net:3001/ I download qgsAzimuth.zip archieve with plugin and test it: create new feature and try to zoom to full extent of the layer. New feature appears on map and in attribute table, but feature count don't increase too.
Сan it is related to that addition takes place through "qgsDataProvider" not throught "QgsVectorLayer"?
