[OpenLayers-Users] Spatial Filter parameter for WFS GetFeature

[bartvde at osgis.nl]

Hi,

you need to specify filterType. The control will take care of providing
the values. So:

var control = new OpenLayers.Control.GetFeature({
  ..
  filterType: OpenLayers.Filter.Spatial.INTERSECTS
  ..
});

Best regards,
Bart
