[Users] PrintPreview Problem: Map is only 1px

[Robert Buckley]

Hi,

i am desperately trying to add a simple printing button to my app. Using this 
example, I wanted to print the mapPanel with an OSM background, however the map 
is only 1px and the pdf is broken.


Here is my app..the print button is in the mappanel´s bottom bar.

here is my code for the mappanel

var mapPanel = new GeoExt.MapPanel({
                  //  title: "Map",
                    region: "center",
                    width: 800,
                    map: map,
                    layers: [gsat, ghybrid,mapnik, layer, vr_wea],
                    tbar: [toolbarItems],
                    bbar: [{
                        text: "Print...",
                            handler: function(){
                        // A window with the PrintMapPanel, which we can use to 
adjust
                        // the print extent before creating the pdf.
                        printDialog = new Ext.Window({
                        title: "Print Preview",
                        width: 350,
                        height: 500,
                        items: [{
                            xtype: "gx_printmappanel",
                            // use only a PanPanel control
                            map: {controls: [new 
OpenLayers.Control.PanPanel()]},
                            sourceMap: mapPanel,
                            printProvider: printProvider
                        }],
                        bbar: [{
                            text: "Create PDF",
                            handler: function(){ 
printDialog.items.get(0).print(); }
                        }]
                        });
                    printDialog.show();
                    }
                }]

                });

thanks for any hints,

Robert
