I'm using the GWT Maps V3 Api from https://github.com/branflake2267/GWT-Maps-V3-Api

After finding directions on the map, I'm trying to clear the previous ones before finding new.

In DirectionsRenderer:

  /**
   * This method specifies the map on which directions will be rendered. Pass null to remove the directions from the map.
   * @param mapWidget
   */
  public final void setMap(MapWidget mapWidget) {
    setMapImpl(mapWidget.getJso());
  }

  private final native void setMapImpl(MapImpl map) /*-{
    this.setMap(map);
  }-*/;

I'm trying to pass:

directionsDisplay.setMap(null);

which results in NPE:

Caused by: java.lang.NullPointerException: null
    at com.google.gwt.maps.client.services.DirectionsRenderer$.setMap$(DirectionsRenderer.java:50)

Anyone used this API and knows how to clear directions from the map widget?
