[Users] Error while Creating PDF via mapfish-printmodul

[Kai Volland]

Hi everybody,

i try to create a print form where i can type in a title and a comment 
quite like this:
  http://api.geoext.org/1.0/examples/print-form.html

When i click the "Create PDF"-Button i get this error:

/map.getUnits is not a function/ --> PrintProvider.js (Zeile 383)

I really don't know how  i could fix it.

Maybe anyone can help me.

Kind regards

Kai

And here comes the code:

/   // print
     // SIMPLEPRINT

     var printProvider = new GeoExt.data.PrintProvider({
         method: "GET", // "POST" recommended for production use
         capabilities: printCapabilities, // provide url instead for 
lazy loading
         customParams: {
             imageurl: "FAKE.png",
         }
     });

     var printPage = new GeoExt.data.PrintPage({
         printProvider: printProvider
     });


     var form = new Ext.FormPanel({
         region: "east",
         labelWidth: '30%',
         frame:true,
         title: 'Metadata',
         width: '100%',
         items:[{
             width: '70%',
             xtype: "textfield",
             fieldLabel: 'Title',
             name: 'mapTitle',
             plugins: new GeoExt.plugins.PrintPageField({
                 printPage: printPage
             })
             },{
             width: '70%',
             xtype: "textarea",
             fieldLabel: 'Comment',
             name: 'comment',
             plugins: new GeoExt.plugins.PrintPageField({
                 printPage: printPage
             })
         }],
         buttons:[{
             text: 'Create PDF',
             handler: function() {
                 printProvider.print(printPage);
             }
         }]
     });



     var action2 = new GeoExt.Action({
         map: map,
         cls: 'x-btn-text-icon',
         tooltip: 'Create PDF',
         icon: imagePath + '/pdf.png',
         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",
                 layout: "fit",
                 width: 350,
                 autoHeight: true,
                 items: [{
                     xtype: "gx_printmappanel",
                     sourceMap: mappanel,
                     printProvider: printProvider
                     },
                     form
                 ]
             });
             printDialog.show();
         }
     });
     actions["print"] = action2;
     toolbarItems.push(action2);/
