GeoExt printPage cannot handle WFS vector features

Question

I recently added the print function to my GeoExt web application, using

<script type="text/javascript"src="http://localhost:8080/geoserver/pdf/info.json?var=printCapabilities"></script>

to define the printCapabilities variable,

        var printProvider = new GeoExt.data.PrintProvider({
            method: "GET", 
            url: "localhost/geoserver/pdf", 
            capabilities: printCapabilities
        });

for the print provider and within the mapPanel

bbar: ["->", {
                text: "Print...",
                handler: function() { 
                    var printDialog = new Ext.Window({
                            items: [new GeoExt.PrintMapPanel({
                                sourceMap: mapPanel,
                                printProvider: printProvider,
                                    listeners: {
                                    "loadcapabilities": function() {
                                    var printPage = new GeoExt.data.PrintPage({
                                        printProvider: printProvider,
                                        customParams: {
                                            mapTitle: "LVR WebGIS",
                                            comment: "created with GeoExt"
                                        }
                                    });
                                        printPage.fit(mapPanel, true);
                                        printProvider.print(mapPanel, printPage);
                                    }
                                    },

                                })
                            ],
                         bbar: [{
                                text: "Create PDF",
                                handler: function() {
                                    printDialog.items.get(0).print();
                                }
                            }]
                    });
                printDialog.show();
                }
            }],

to add the function to my mapPanel. Regarding this, I have two issues to be solved:

1.) the printPage popping up does not contain anything but the button saying "Create PDF". There should be a preview of the map to print, right?

2.) when some WFS vector features are displayed in the map, the print function does not work properly anymore. It opens a new tab in my browser but does not create the PDF. Instead, the new tab is left about:blank.

What am I doing wrong here? Is the information I provided enough for you guys to help me solve the problem? Thanks a lot for your help!

Answer 1

Shouldn't the print provider set up refer to localhost:8080 instead of localhost/ ? if they really are on different ports then you probably need a proxy to handle the same origin requirements.
