Hi Jonathan, Although not a desirable effect, this is the expected behaviour. We're experiencing the exact same behaviour in one of our maps. The vendorOption "group" actually groups the geometries based on the label attribute only, but does not take into account the other attributes that relate to the geometries and that are used for the visualisation. For another project we pre-processed the Tele Atlas data first, grouping the geometries not only by name, but also other attributes (e.g. "Form of Way", "Network Class", "Direction of Traffic Flow"). In order not to have one geometry containing all the "High Streets" in a country, we then performed an ST_Dump. In short: pre-process the data and don't rely on the vendorOption "group" for this kind of visualisation. Another approach could be to refactor to the code in GeoServer so the vendorOption "group" actually takes into account the other attrributes that are declared in the <ogc:filter> tags of the <Rule>.

Hi List,I'm getting some anomalous behaviour and figured I'd ask if it was as-designed or if it seems like a bug. I have two layers coming from two different tables. One contains Primary Roads (green), the other A-Roads (red). Each has a single SLD which draws the features and labels them. The only different between the two SLD's is the colours. I'm using the grouping feature:<VendorOption name="group">yes</VendorOption> Any given road section is only geographically represented once between these two layers - there is no overlapping. But from a labelling perspective a road's name can appear in both layers. So the A444 could be a mixture of primary road and A-Road as thus: -------====------- My issue is that the grouping seems to happen across layers. So I have a Primary road (A444) being labelled with the colour scheme of the A-road because there are three sections of A444 in the A-road layer (there are 63 in the Primary Road layer). The A-Road A444 sections are all 60 pixels north under "Nuneaton". The label should be Primary Road green. Should this happen? I expected the grouping to only happen within a single layer, not across layers. There's no mention of which way it's supposed to work in the help.
