When I’m zoomed way into the map, the vector layer doesn’t highlight – whereas the smaller areas (smaller gml files…around 70K) around it highlight without issue. So I’m not sure what’s going on – I was using the GML (deprecated) layer, but I switched over to the Vector layer and I’m seeing the same issue. Does anyone have any ideas? I don’t think my code will be particularly helpful, but I’ll include it anyway….<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> Creating the layer… <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal style='text-autospace:none'><span style='font-size:10.0pt;font-family:"Courier New";background:white;mso-highlight:white'> <span style='color:black'>gmlLayer</span> <span style='color:#5C5C5C'>=</span> <b><span style='color:#0000C0'>new</span></b> <span style='color:black'>OpenLayers</span><span style='color:#5C5C5C'>.</span><span style='color:black'>Layer</span><span style='color:#5C5C5C'>.</span><span style='color:black'>Vector</span><span style='color:#5C5C5C'>(</span> <span style='color:#005C00'>"GML"</span><span style='color:#5C5C5C'>,</span> <span style='color:#5C5C5C'>{</span><span style='color:black'>strategies</span><span style='color:#5C5C5C'>:</span> <span style='color:#5C5C5C'>[</span><b><span style='color:#0000C0'>new</span></b> <span style='color:black'>OpenLayers</span><span style='color:#5C5C5C'>.</span><span style='color:black'>Strategy</span><span style='color:#5C5C5C'>.</span><span style='color:black'>Fixed</span><span style='color:#5C5C5C'>()],</span></span><span style='font-size:10.0pt;font-family:"Courier New"'><o:p></o:p></span></p><p class=MsoNormal style='text-autospace:none'><span style='font-size:10.0pt;font-family:"Courier New";background:white;mso-highlight:white'> <span style='color:black'>protocol</span><span style='color:#5C5C5C'>:</span> <b><span style='color:#0000C0'>new</span></b> <span style='color:black'>OpenLayers</span><span style='color:#5C5C5C'>.</span><span style='color:black'>Protocol</span><span style='color:#5C5C5C'>.</span><span style='color:black'>HTTP</span><span style='color:#5C5C5C'>({</span></span><span style='font-size:10.0pt;font-family:"Courier New"'><o:p></o:p></span></p><p class=MsoNormal style='text-autospace:none'><span style='font-size:10.0pt;font-family:"Courier New";background:white;mso-highlight:white'> <span style='color:black'>url</span><span style='color:#5C5C5C'>:</span> <span style='color:#005C00'>"ajax/ajaxProxy.cfm?proxyURL=http%3A%2F%2Fmywebsite.com%3A8080%2Fgeoserver%2Fwfs%3Frequest%3Dgetfeature%26service%3Dwfs%26version%3D1.0.0%26srsname%3Depsg%3A900913%26typename%3Dpg_service_area%26filter%3D%3Cogc%3AFilter%20%20xmlns%3Aogc%3D%22http%3A%2F%2Fogc.org%22%3E%3Cogc%3AFeatureId%20fid%3D%22service_area.12342%22%2F%3E%3C%2Fogc%3AFilter%3E"</span><span style='color:#5C5C5C'>,</span></span><span style='font-size:10.0pt;font-family:"Courier New"'><o:p></o:p></span></p><p class=MsoNormal style='text-autospace:none'><span style='font-size:10.0pt;font-family:"Courier New";background:white;mso-highlight:white'> <span style='color:black'>format</span><span style='color:#5C5C5C'>:</span> <b><span style='color:#0000C0'>new</span></b> <span style='color:black'>OpenLayers</span><span style='color:#5C5C5C'>.</span><span style='color:black'>Format</span><span style='color:#5C5C5C'>.</span><span style='color:black'>GML</span><span style='color:#5C5C5C'>()</span></span><span style='font-size:10.0pt;font-family:"Courier New"'><o:p></o:p></span></p><p class=MsoNormal style='text-autospace:none'><span style='font-size:10.0pt;font-family:"Courier New";background:white;mso-highlight:white'> <span style='color:#5C5C5C'>})</span></span><span style='font-size:10.0pt;font-family:"Courier New"'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Courier New";background:white;mso-highlight:white'> <span style='color:#5C5C5C'>});</span></span><span style='font-size:10.0pt;font-family:"Courier New";color:#5C5C5C'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Courier New";color:#5C5C5C'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Courier New";color:#5C5C5C'>Each time a click occurs, a new url is passed in.
