Our data model has few attributes with species lists. E.g. animals, plants, fungi,…, all are in different attributes. When querying data, species names are shown in separate columns of the query table, and this is fine. But, when adding such query results into a report, as a map layer, it is not possible to select a single column as a source for labels. For tables in reports, the problem is solved by a ‘Computed column’ and a simple expression. But for map labels, this doesn’t work. The virtual ‘Computed column’ is available in the list of columns that can be used for labels, but when such a report is run an error occurs saying ’ … Problem rendering: Could not find ‘Map_labels’ in the FeatureType (smart:null), available attributes are: [the_geom, fid, Source… '. It seems, that virtual ‘Computed colums’ do not work for map labeling. Is there any way to get this working?
Thanks in advance,
