Hello Sarah,
Yes, you could define a BBOX filter in your WFS protocol to fetch
just a portion of the features you want. See an example of BBOX
filtering :

Any hints on this?
Am I right to think that if I use BBOX with my wfs that my linked
FeatureStore is only loading such number of features?
And why did including ext-override-ajax.js not work?
Thanks!

Hi list,
I have a wfs and want to publish my data via a FeatureStore.
If I load it with:
fields: [{name: .....}],
proxy: new GeoExt.data.ProtocolProxy({
protocol: new OpenLayers.Protocol.WFS({
url:
...
})
})
there is a long loading time because of high number of features.
If I want to use
layers: wfsLayer
instead of protocol option (because I use BBOX filter for wfs reducing
features from 10000 to some hundred) I get an error that proxy is
undefined.
My wfs layer is:
wfsLayer = new OpenLayers.Layer.Vector("mywfs",
{styleMap: wfsStyle,
displayInLayerSwitcher: false,
strategies: [new OpenLayers.Strategy.BBOX()],
protocol: new OpenLayers.Protocol.WFS({
featureNS: "myNS",
featureType: "mylayer",
version: "1.1.0",
...
})
});
I included a proxy script which is working.
I searched and found that I have to add ext-override-ajax.js to my
GeoExt build but that did not help.
What I`m doing wrong?
Any hints to get better performance for displaying data?
Thanks
best regards
Sarah
