You can check for the layer that a feature was selected on in the event handler and perform different actions based on that. Why would you need a second control for that? > Does Control.SelectFeature really needs to be a singleton ? No, you can have as many SelectFeature controls as you want. But the way it works is that it needs to put the layers to select from at the top of the layer stack, and this is why you should just have one SelectFeature contorl *activated* at a time. > Additionaly: why on Chrome I can have two different controls attached to my > two > layers and on FF I can't ? This must have to do with the way events are handled on SVG elements. But I cannot tell you exactly why. > This doesn't work on FF (lower left point click is not active) but works on > Chrome: > http://www.parconord.milano.it/ol_ko.html > > Should I file a bug report ? No, because having two active SelectFeature controls is not supported. If you want smarter feature selection, have a look at http://trac.openlayers.org/changeset/9739 - this could become the way we handle feature selection in the future.
