<html><head></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>Hi,</div><div><br></div><div>I use the following example of geolayers to test GetFeatureInfo (it works, so this can be no proxy-issue, also OpenLayers and GeoServer run on the same server). But when I copy the (what I think) relevant parts into my own code, it is not working anymore (after clicking on the line the text switches from "Click on the map to get feature info" to "Loading... please wait..." and that's it). So it would be great to know what the minimum requirements for this method are? And if it is possible to limit the output to some properties of the layer?</div><div><br></div><div>Maybe the problem is the line</div><div><br></div><div><blockquote type="cite"><font
