Raphael,
I don't know of a simple function to do it, but if you get the line as a
feature, it should be as easy as:
pointArray = lineFeature.geometry.components;
pointFeatures = [];
for (var i = 0; i < pointArray.length; i++) {
pointFeatures.push( new OpenLayers.Feature.Vector( pointArray[i] ) );
}
"pointFeatures" will then be an array of point vector features, suitable for
sending to layer.addFeatures.
