Hi, I didn't have a patch. The only thing I have is a new handler and a new control.
I can send you that code, if you want and you can include and test it.

Want to share I'm interested to test your code to select a layer.GML witch contain markers. I have 2 layers of markers but only one layer can be selected by [CODE] selectControl = new OpenLayers.Control.SelectFeature(map.layers[1], {onSelect: onFeatureSelect, onUnselect: onFeatureUnselect}); {/CODE] In which folder I must to download your patch Thanks Andre Pereira de Matos wrote: > > Forgot the code, sorry. > > Best Regards, > André Matos > http://maps.sapo.pt > > > -----Original Message----- > From: Andre Pereira de Matos > Sent: sexta-feira, 16 de Janeiro de 2009 11:02 > To: 'Andreas Hocevar' > Cc: [email protected]; [email protected] > Subject: RE: [OpenLayers-Dev] New DragFeature Control and > SelectFeatureControl cross layers.
