There's a demo on the GeoExt site that's really similar to your question,
http://dev.geoext.org/trunk/geoext/examples/mappanel-viewport.js
Very near the top of that javascript code, above the
"Ext.onReady(function() ", they define var mapPanel. That should take
care of mapPanel not being defined.

Hi,
I´ve been hitting my head against a wall all evening trying to get a treepanel
to work in a viewport.
I always get the error message Mappanel not defined!!...this is because mapPanel
is declared underneath the tree, but I can´t put the tree under the viewport
either.
It´s late and i´m lost. Can anyone help me out?
.....
this rest of the code just defines the grids and the layers.
.....
var tree = new Ext.tree.TreePanel({
region: "west",
title: "Map Layers",
width: 200,
autoScroll: true,
enableDD: true,
lines: false,
rootVisible: false,
root: new GeoExt.tree.LayerContainer({
layerStore: mapPanel.layers,
expanded: true
})
});
new Ext.Viewport({
layout: "border",
items: [{
region: "north",
contentEl: "title",
height: 50
}, {
region: "center",
id: "mappanel",
title: "Map",
xtype: "gx_mappanel",
map: map,
layers: [gsat, mapnik,layer_wea, layer_zgbgrenze],
minScale: 500000,
maxScale: 100000,
numZoomLevels: 2,
center: [1169180, 6843865],
zoom: 9,
split: true
}, {
region: "west",
title: "Karteninhalt",
items:[],
width: 200,
split: true
}, {
region: "east",
split: true,
collapsed:true,
collapsible:true,
xtype: 'tabpanel',
title: 'WEA',
width: 500,
items: [
attribgridPanel_wea,attribgridPanel_gas,attribgridPanel_wasser
]
}]
});
var mapPanel = Ext.getCmp("mappanel");
});
Thanks,
Rob
