[Users] Grouping kml layers in a tree panel

[Andreas Hocevar]

Hi,

your treeConfig is generated with new OpenLayers.Format.JSON().write(). You have to create the configuration directly, otherwise you will lose all functions that you configure. Your tree configuration should look like

var treeConfig = {
    ...
}; 

instead of

var treeConfig = new OpenLayers.Format.JSON().write([{
    ...
}]);

And in your treepanel config, instead of providing

    children: Ext.decode(treeConfig)

you have to provide

    children: treeConfig

Regards,
Andreas.
