[OpenLayers-Users] Can't define hover behavior on a Feature.Vector or a Layer.Vector

[Diego Guidi]

Why you can't define a stylemap for "default" feature visibility?
You need some computation inside the loop to build a style for the feature?

Anyway, try to pass the style as a Style objectdirectly in the Vector
constructor, ie:
var yourstyle = new Openlayers.Style({strokeWidth: "#123456"
,strokeColor: "#123456", fillColor: "#123456", fillOpacity:
"#123456"});
var fv = new OpenLayers.Feature.Vector(linearRing, {/*empty
attributes*/, yourstyle);
