[OpenLayers-Users] Handling double click

[Eric Lemoine]

Hi. I'm not sure i understand. Do you use OL click handler or have you
implemented your own double click handler? OL click handler supports
double click. So use that handler with appropriate options, in part
use stopClick:true and make sure you activate the handler after the OL
controls. Tell me how it goes. Eric
