[GeoNode-devel] errors with style creation during layer upload to PostGIS

Hi Simone
I will try the reset and let you know.
I just checked the approach of using a more sophisticated approach to
name a layer, and this is solving the problem.
Right now when uploading a new layer, GeoNode checks if there is
already a layer with the same name in the prefix. If this is the case,
it appends a +1 to the layer name. This create a problem when removing
the layer and reloading it a second time, because for some reason
GeoServer still has that name in same part of the catalog (I believe
the problem is connected with styles catalog, as it raises when
GeoNode tries to create a style for the layer).
If we use a more complex naming mechanism this will be sorted - I just
tried a primitive approach to append a random number to the layer name
and it works.
So, definitely I can create a ticket: we can discuss if we should fix
this at GeoServer lever (cleaner for sure), or at GeoNode level using
a more complex layer naming mechanism
thanks to you, Alessio and GeoSolutions for helping with this!
Paolo
