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.

It doesn't work because when you use the PointStacker, the original attributes are lost so you can't (for now) have a dynamic style according to an attribute's value, STATE in your case.
