[OpenLayers-Users] How to - severable clickable WFS layers ?

[Asle Benoni]

Hi,
I just wonder how I know if I have OpenLayers 2.8? I have downloaded from
trunk but the date for OpenLayers.js is 31.03.2009. Or do I have to grab
some special files. *map.layers* is my arrayname?

I tried your suggestion but when I write:
selectControl = new OpenLayers.Control.SelectFeature(*map.layers*,{onSelect:
onFeatureSelect, onUnselect: onFeatureUnselect});
           map.addControl(selectControl);
           selectControl.activate();
           function onPopupClose(evt) {
                selectControl.unselect(selectedFeature);
            }
I get this error in Firebug and the page is blank:
*layer.renderer is undefined
*
Does this mean I am still using too old OpenLayers.js?
