Hi all,
I have a problem with a WFS Vector layer that return data in geoJSON format.
I have implemented this strategies:
"strategies": [
new OpenLayers.Strategy.BBOX(),
new OpenLayers.Strategy.Cluster({treshold:3})
]
this is my layer style configuration:
"styleMap": new OpenLayers.StyleMap({
"default": new OpenLayers.Style({
externalGraphic: "core/stub/simpleIcon.png",
label: "${label}",
cursor: "pointer"
},
{
context:{
externalGraphic: function(feature) {
if (feature.cluster)
feature.attributes.externalGraphic =
"core/stub/clusterIcon.png";
return feature.attributes.externalGraphic;
},
label: function(feature) {
return feature.cluster ? feature.cluster.length :
"";
}
}
})
})
Well, the features returned have always cluster attribute, also if the
feature is isolated there is a cluster array that contains a single
feature. In this manner I see always cluster icons, also on single feature.
Anyone has some ideas?
Thanks a lot.
Giuseppe
