[OpenLayers-Users] Uncaught TypeError: Cannot read property 'x' of null - popup problem

[Robert Buckley]

Hi,

I´ve just added a simple wms popup to a map which has worked in the past and now 
I get the error 

"Uncaught TypeError: Cannot read property 'x' of null"

Anyone any idea how to solve this?


yours,

Rob

// create the popup
var featureInfo = new OpenLayers.Control.WMSGetFeatureInfo({
queryVisible: true,
highlightOnly: true,
maxFeatures: 5,
maxFeatures: 1
});



featureInfo.events.on({
    getfeatureinfo: function(e) {
        new GeoExt.Popup({
            title: "<b><h2>Position: 
</h2></b>"+mapPanel.map.getLonLatFromPixel(e.xy).transform(epsg900913, 
epsg4326),
            width: 400,
autoHeight: true,
layout: 'accordion',
bodyStyle: 'background-color:#FFF;,font-size:14px;',
            autoScroll: true,
            maximizable: true,
            map: map,
            lonlat: mapPanel.map.getLonLatFromPixel(e.xy),
            html:e.text,
unpinnable:true,
anchored: true,
shadow: true,
listeners: {
                    close: function() {
                        // closing a popup destroys it, but our reference is 
truthy
                        popup = null;
                    }
}
        }).show();
    }
});

map.addControl(featureInfo);
featureInfo.activate();
