[Users] Geoext - Print Error

[adams]

Dear list,

we implemented the print-panel (geoext 0.7) as follows:

     var printProvider = new GeoExt.data.PrintProvider({
         method: "GET", // "POST" recommended for production use
         capabilities: printCapabilities // from the info.json script in 
the html
     });

     printPage = new GeoExt.data.PrintPage({
         printProvider: printProvider,
         customParams: {
             mapTitle: "Geoext is cool!"
         }
     });

     printExtent = new GeoExt.plugins.PrintExtent({
         showOnInit: false,
         printProvider: printProvider
     });

and further down:

     mapPanel = new GeoExt.MapPanel({
         ...
         plugins: [printExtent],
         ....

This was derived from the examples "print-extent" and "print-form". When 
opening the print panel in our client, I get an error "page.center is 
null [center: page.center.lon, page.center.lat]" .

Comparing our stuff with the example, I see, that in the form-example a 
method is called:

printExtent.addPage();

doing this another error comes up: "printExtent.addPage is not a function"


Any hint will make me happy and let me pay a drink in Barcelona... ;-)
