[OpenLayers-Users] DrawFeature and FeatureAdded event

[Eric Lemoine]

Mika,

Sture registers a listener on the draw feature control's featureadded
event, not on the layer's. The former is triggered only when a feature
is added as a result of feature drawn by the user through the draw
feature control. The latter is triggered every time a feature is added
to the layer, whatever the way the feature was created.
