[GeoNode-users] Error when saving style from gxp

[Amedeo Fadini]

Hi everybody,

I'm using Geonode 2.4 insatlled via ppa on Ubuntu server.
I usually publish my layers in geoserver (most of them are sql views
from a Postgis Database that aggregate data from other Mysql db using
foreign tables) and so I prepare also the styles in geoserver and then
synchronize with  geonode -updatelayers command.

I need to add the same layer to a map two or more times, with
different styles: when I try to modify the style from the map editor
in geoexplorer it raise an error and  the style is not saved.
Apache error Log attached below

If I clone the style it raise an error "forbidden" (Cannot delete
style associated with an other layer) but at the ends the new style is
saved.

Any clue?

thanks
