[Users] Popup

[Alex Zeit]

I found solution using OpenLayers.LoadURL:

                   var selFeature;

                   control.events.register("featureselected", this,
function(e) {
                        var url = '
http://www.domain.com/servlet'+e.feature.attributes.id;
                        selFeature = e.feature;
                        OpenLayers.loadURL(url, '', e, createPopup);
                        OpenLayers.Event.stop(e);
                    });

                    var createPopup = function(response) {
                        popup = new GeoExt.Popup({
                            title: 'My Popup',
                            feature: selFeature,
                            width:200,
                            html: response.responseText, //
feature.attributes.sid,  //bogusMarkup, theHtml
                            maximizable: false,
                            collapsible: true
                        });
