I'm trying to reload a GeoExt.data.FeatureStore changing url. This is my code:
var vecLayer = new OpenLayers.Layer.Vector("vector", {
protocol: new OpenLayers.Protocol.HTTP({
url: '/url',
format: new OpenLayers.Format.GeoJSON()
}),
strategies: [new OpenLayers.Strategy.Fixed()]
});
var store = Ext.create('GeoExt.data.FeatureStore', {
layer: vecLayer,
fields: [
{name: 'name', type: 'string'},
{name: 'elevation', type: 'float'}
],
autoLoad: true
});
mycombo.addListener('change', function() {
vecLayer.protocol.url = "/url2";
vecLayer.refresh();
});
I can see the request is made in Firebug console, but the url is "/url" not "/url2" as I expect. Also tried with
store.proxy.url = "url2";
since FeatureStore inherit from Ext.data.Store but no luck.
I've got it! I have to replace the protocol:
mycombo.addListener('change', function() {
var proto = new OpenLayers.Protocol.HTTP({
url: new_url,
format: new OpenLayers.Format.GeoJSON()
});
vecLayer.protocol = proto;
vecLayer.refresh();
});
