Hi list (or should i say hi Eric :)
I have a problem with using cluster strategy. I use gml file exported
with geoserver getFeature request to display my vector layer.
When using "normal" gml layer i get my features displayed without
problem, so i guess that means my GML file is valid:
myGmlLayer= new OpenLayers.Layer.GML("My name", "fileFromGeoserver.gml");
When using that same file but with cluster strategy, i get following
error in my firebug window
feature.geometry is null
OpenLayers.js (line 535)
return exist;},shouldCluster:function(cl...ck:this.merge,scope:this});return
true;}
this is my code for cluster layer:
var style = new OpenLayers.Style({
pointRadius: "${radius}",
}, {
context: {
radius: function(feature) {
return Math.min(feature.attributes.count,4) + 3;
}
}
});
myGmlLayer= new OpenLayers.Layer.Vector("GML", {
strategies: [new
OpenLayers.Strategy.Fixed(), new
OpenLayers.Strategy.Cluster()],
protocol: new OpenLayers.Protocol.HTTP({
url: "fileFromGeoserver.gml",
format: new OpenLayers.Format.GML()
}),
styleMap:new OpenLayers.StyleMap({
"default": style,
}
})
});
Should my features inside gml file have some particular syntax for
geometry column? Hmm i dont think so, because it gets displayed
properly with OpenLayers.Layer.GML...
Any thoughts about it? I can post a bit of gml file if necessary..
Regards,
Ivan
