Hi folks, After a thorough revision of my code, I noticed that when testes OL 2.11 I added this line of code. OpenLayers.Layer.Vector.prototype.renderers = ["SVG2", "VML", "Canvas"];
For some reason this screws up my OL 2.10. After deleting this, OL works fine. Can anyone explain what that line of code does ? What I cant get to work is the property cursor:"pointer" in the style. I will keep you posted. Pointers are always welcome Ricardo 2011/6/7 Ricardo Bayley <[email protected]> > Hi Folks, > > I have this code > > * var q = arguments[0];* > * var format = new OpenLayers.Format.GeoJSON({* > * 'internalProjection': map.baseLayer.projection, // > 900913* > * 'externalProjection': new > OpenLayers.Projection('EPSG:4326')* > * });* > * var features = format.read(js);* > * q.layer.addFeatures(features);* > * > * > * var z = map.getZoomForExtent(q.layer.getDataExtent())-1;* > * map.setCenter(q.layer.getDataExtent().getCenterLonLat(), z);* > > > so far, everything works fine.
