My goal is to have WFS features loaded onto the map before I call a function
that accesses these features. The catch is I need to keep the WFS features
hidden, cause I don't really need to see them. I have my code like this:
var wfs_layer = new OpenLayers.Layer.Vector("wfs
layer", {
strategies: [new OpenLayers.Strategy.BBOX(),new
OpenLayers.Strategy.Fixed()],
protocol: new OpenLayers.Protocol.WFS({
version: "1.1.0",
url: "/geoserver/wfs",
featureType: wfs_feat_type,
featureNS: "http://geoserver.sf.net";,
featurePrefix: "sde",
srsName: "EPSG:900913",
geometryName: "SHAPE"
})
});
wfs_layer.setVisibility(false);
map.addLayers([wfs_layer]);
Since the layer is not visible, it doesn't load the features. So I call the
following:
map.getLayersByName(l_name+" wfs")[0].strategies[1].load();
The problem with this is that it behaves inconsistently. Sometimes it won't
load any features, sometimes it will only load a few features, and at times
it will load all the features. I don't understand why it does that. Does
anyone know why?
I tried to do this too: new OpenLayers.Strategy.Fixed({preload:true}), but
some of my layers are too large and it crashes my browser. So that's out of
the question. Any ideas? Thanks.
