Title: About 414 - NPE when dragging a source on the Map.

Because of a rework of this method, the DataSource sent to the LayerModel was null. The inner DataSource of EditableSource instances is lazy initialized. To linked an EditableSource to a DataSource, we must call open. I call close too so that we won't have problems, with OCCounterDecorator for instance.
