Hello all,
I am using a vector layer to highlight certain areas on a mapping application
of I've created. Each click resets the protocol url to a new location and
refreshes the layer, pulling down a new feature (in GML, from GeoServer).
I'm having a strange issue - one of those GML files being pulled down by the
vector layer is very large (800K). When I'm zoomed way into the map, the
vector layer doesn't highlight - whereas the smaller areas (smaller gml
files...around 70K) around it highlight without issue. So I'm not sure what's
going on - I was using the GML (deprecated) layer, but I switched over to the
Vector layer and I'm seeing the same issue. Does anyone have any ideas? I
don't think my code will be particularly helpful, but I'll include it anyway....
Creating the layer...
gmlLayer = new OpenLayers.Layer.Vector( "GML", {strategies: [new
OpenLayers.Strategy.Fixed()],
protocol: new OpenLayers.Protocol.HTTP({
url:
"ajax/ajaxProxy.cfm?proxyURL=http%3A%2F%2Fmywebsite.com%3A8080%2Fgeoserver%2Fwfs%3Frequest%3Dgetfeature%26service%3Dwfs%26version%3D1.0.0%26srsname%3Depsg%3A900913%26typename%3Dpg_service_area%26filter%3D%3Cogc%3AFilter%20%20xmlns%3Aogc%3D%22http%3A%2F%2Fogc.org%22%3E%3Cogc%3AFeatureId%20fid%3D%22service_area.12342%22%2F%3E%3C%2Fogc%3AFilter%3E",
format: new OpenLayers.Format.GML()
})
});
Each time a click occurs, a new url is passed in. I've verified that the URL
for the large GML file returns a valid GML file. There's nothing particularly
strange about it.
setUrl = function(url){
gmlLayer.protocol.options.url = url;
gmlLayer.refresh();
};
Let me know if there's anything else that would be particularly diagnostically
helpful.
Aaron
