E.g. > > feature.style = OpenLayers.Feature.Vector.style["delete"]; why does the renderIntent approach not work? It does work for controls like SelectFeature. From what I see in the code, the renderIntent of the feature is changed in createSymbolizer called from drawFeature, which should use the renderIntent of the feature (in this case, 'hidden'). Unless the style map doesn't contain a 'hidden' style, in which case it would default back to ... um ... 'default' :) Paul _______________________________________________ Users mailing list [email protected] http://openlayers.org/mailman/listinfo/users
