applyPosition() =>
```
        this.target.mapPanel.map.setCenter(
            this.position, this.coordsRecenterZoom);

        if (this.showCenter) {
            // show a point feature to materialize the center
            var feature = new OpenLayers.Feature.Vector(
                new OpenLayers.Geometry.Point(this.position.lon,
                                              this.position.lat),
                this.coordsRecenteringStyle || {}
            );
            this.vectorLayer.removeAllFeatures();
            this.vectorLayer.addFeatures([feature]);
        }
```

=> map.setCenter() and add the missing style !
