// FIXME: overrides the behaviour of UpdateSelectionAction. Doesn't update
// the enabled state based on the current selection because
// it doesn't depend on it.
// The action should be enabled/disabled based on whether there is a least
// one modified object in the current dataset. Unfortunately, there is no
// efficient way to find out here. getDataSet().allModifiedPrimitives() is
// too heavy weight because it loops over the whole dataset.
// Perhaps this action should be a DataSetListener? Or it could listen to the
// REQUIRES_SAVE_TO_DISK_PROP and REQUIRES_UPLOAD_TO_SERVER_PROP properties
// in the OsmLayer?
