[GeoNode-users] Custom background layers not in Thumbnail

Hi,
Yes, this is waht i'm doing. I started debugging, and found out that tiles with really weired bounding box values are send to geonode.maps.views.map_thumbnail.
but some of the tiles of wms_webatlas have correct bounding boxes. Also the bounding boxes of the geoserver-Wms are correct.

What may be the problem? I guess it has something to do with the layer definition..

Any further ideas?

This are the images sended to map_thumbnail():

Hi, are you saving the thumbnail through the set thumbnail button in map detail -> edit map?
This is the only way to get the background rendered in the thumbnail

Hi,
I created custom map base layers, which are added to every newly
created map. When saving this map, the thumbnail is created without the
basemap on it.

To define the basemaps, i added a gxp plugin, correspondingly to the
BingSource, based on a WMS. May be I missed something?
Do you have any idea, what I have done wrong?

Thank you so much for your help.

Here is the code:

gxp.plugins.WebAtlasFarbeSource = Ext.extend(gxp.plugins.LayerSource, {

    ptype: "gxp_webatlasfarbesource",

    title: "WebAtlasDE Farbe",

    webAtlasFarbeTitle: "WebAtlasDEFarbe",
    url: "https://sg.geodatenzentrum.de/wms_webatlasde__UUID",
    attribution: "© GeoBasis-DE / <b>BKG</b> ("+year+")",
    createStore: function() {

        var layers = [
             new OpenLayers.Layer.WMS(this.webAtlasFarbeTitle,
                                   this.url,
                                   {layers: ["webatlasde"],
                                   format:"image/png",
                                   tiled: true
                                   },
                                   {
                                       attribution : this.attribution

        ];

        this.store = new GeoExt.data.LayerStore({
