Hi Giambattista and welcome in the dev list
Thank-you Alessio for the quick response.
I have a question just to learn something new: is it the same thing to
define the M2M relation on the new object side or use add_class to resource
base like in this class?
I see in Giambattista log the line
producer.geoserver_upload_layer(payload)
Giambattista: does the update operation imply the creation or replacement
of the layer related to domain_area?
If this is the case have you checked that integrated authentication between
geonode and geoserver is working as expected?
