Just another question also. I still have not got this filtering to work even if I see the cql_filter params in the WMS request. I wonder also since I generate a variable every time a search is done. Will the newest search params be used on the WMS.getFeatureInfo or do I in some way have to push the new variable to the WMS.getFeatureInfo. I guess the javascript is read once when the page is loaded. I.ex. I use this function<div>
<br></div><div>var filter_param = param;</div><div><span class="Apple-style-span" style="border-collapse:collapse;color:rgb(80,0,80);font-family:arial,sans-serif;font-size:13px"> info = new OpenLayers.Control.WMSGetFeatureInfo({....</span></div>
<div><span class="Apple-style-span" style="border-collapse:collapse;color:rgb(80,0,80);font-family:arial,sans-serif;font-size:13px">...</span></div><div><span class="Apple-style-span" style="border-collapse:collapse;color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px"><div>

}, ......</div><div><br></div><div>Will each click use the new updated "param" or just use the one defined upon page load?</div><div><br></div><div>~asle </div></span></div><div><br><div class="gmail_quote">
