Hello anyone have any ideas why I'm not getting features back from the GetFeatureInfo when I use the google hybride as base map?<br><br>thanks!<br><br>alessandro ferrucci<br><br><div class="gmail_quote">On Wed, Oct 21, 2009 at 1:17 PM, Alessandro Ferrucci <span dir="ltr"><<a href="mailto:alessandroferrucci@gmail.com">alessandroferrucci@gmail.com</a>></span> wrote:<br>

I want to attach click mouse handler on POI layer for GetFeatureInfo. Whenever I click the mouse, I don't get any features back. I think it has something to do with projection and mouse location ? ...not quite sure.<br>
<br>Just as an aside, when I view my POI layer using Geoserver's demo functionality, it gets back all features fine, this is reason I think it has something to do with projection that I attach to my mouse handler or something.<br>
