I'm using PointStacker to aggregate several point features that are too close in certain views and produce a more readable map. I also have a filter to show a different color symbol according to the value of the attribute STATE.
The second filter worked well when I wasn't using the PointStacker transformation. Now my map is correctly showing the clustering points but doesn't show any point that is alone neither shows the disaggregated points of a cluster when zooming in.
This is my SLD, could you please tell me what's wrong with it? Geoserver is validating it and previews the legend correctly.
