I am trying to import the print plugin within an application built using the Opengeo Suite sdk and I have run into issues as is described in the following thread https://getsatisfaction.com/opengeo/topics/doubts_about_the_use_of_print_from_openlayers_ready_gxp
After having followed all the instructions provided, I still cannot get the print plugin the work. The print button appears but I get the message
Uncaught TypeError: undefined is not a function
This seems to be on the following line:
var scaleLine = new OpenLayers.Control.ScaleLine({ ...
I have also tried using an alternate approach wherein I have a handler for the print button as is shown below:
var app = new gxp.Viewer({
portalConfig: {
layout: "border",
region: "center",
...
...
...
// layer sources
sources: {
local: {
ptype: "gxp_wmscsource",
url: "/geoserver/wms",
version: "1.1.1"
},
osm: {
ptype: "gxp_osmsource"
},
geonetwork: {
ptype: "gxp_cataloguesource",
url: "/geonetwork/srv/en/csw",
title: "Geonetwork"
},
ol: {
ptype: "gxp_olsource"
}
},
// map and layers
map: {
id: "mymap", // id needed to reference map in portalConfig above
title: "Map",
//projection: "EPSG:900913",
//center: [-10764594.758211, 4523072.3184791],
projection: "EPSG:4326",
center: [-97, 38],
zoom: 3,
layers: [{
source: "ol",
type: "OpenLayers.Layer.WMS",
args: ["World map", "http://vmap0.tiles.osgeo.org/wms/vmap0", {layers: 'basic'}],
group: "background"
}, {
source: "ol",
type: "OpenLayers.Layer",
args: ["Blank"],
visibility: false,
group: "background"
//source: "osm",
//name: "mapnik",
//group: "background"
}//, {
//source: "local",
//name: "usa:states",
//selected: true
//}//, {
//source: "google",
//name: "ROADMAP",
//group: "background"
//}
],
bbar: [{
text: "Print...",
handler: showPrintWindow
}],
items: [{
xtype: "gx_zoomslider",
vertical: true,
height: 100
}]
}
});
function showPrintWindow() {
var printWindow = new Ext.Window({
title: "Print",
modal: true,
border: false,
resizable: false,
width: 360,
autoHeight: true,
items: new GeoExt.ux.PrintPreview({
autoHeight: true,
printMapPanel: {
// limit scales to those that can be previewed
limitScales: true,
// no zooming on the map
map: {controls: [
new OpenLayers.Control.Navigation({
zoomBoxEnabled: false,
zoomWheelEnabled: false
}),
new OpenLayers.Control.PanPanel()
]}
},
printProvider: {
// using get for remote service access without same origin
// restriction. For async requests, we would set method to "POST".
method: "GET",
//method: "POST",
// capabilities from script tag in Printing.html.
capabilities: printCapabilities,
listeners: {
"print": function() {printWindow.close();}
}
},
includeLegend: true,
mapTitle: "PrintMapPanel Demo",
sourceMap: app.map
})
}).show().center();
}
From within the showPrintWindow function the sourceMap is set to app.map. However, when I click on the print button now, I get the error message:
Uncaught TypeError: Object #<Object> has no method 'getProjection' PrintMapPanel.js:176
GeoExt.PrintMapPanel.Ext.extend.initComponent PrintMapPanel.js:176

I am not entirely sure how I can get this working and any help is greatly appreciated.
