Hi Diego,
Thank you for you answer.
That was my first approach.I realized that:
var fv = new OpenLayers.Feature.Vector(linearRing, {}, {strokeWidth: "#123456"
,strokeColor: "#123456", fillColor: "#123456", fillOpacity: "#123456"})
;is the same as:
var fv = new OpenLayers.Feature.Vector(linearRing);fv.style = {strokeWidth:
"#123456" ,strokeColor: "#123456", fillColor: "#123456", fillOpacity: "#123456"}
;The thing is, I'm only defining one style. What I need is a style for
"default" and a style for "select" but OpenLayers.Feature.Vector doesn't
support an OpenLayers.StyleMap like the OpenLayers.Layer.Vector does. If an
OpenLayers.StyleMap was supported I could define a renderIntent and therefore
maybe implement the select behaviour.

or a Layer.Vector
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)
