Jody, I tried your suggestion anyway. I made a new store connecting to the exactly the same PostgreSQL schema, but now with "Support on the fly geometry simplification" unchecked. I left my first store (used in my question) unchanged. Then I published the 2 table (US_States and my own table) under the new store.
With these 2 new layers, the piechart SLD works! I mean the SLD with intersection between geometry columnd and WMS_BBOX in its <Geometry> SLD element. The piechart shown as expected (placed on centroid of the appearing part of polygon). This was a quick try. I am sure that Geoserver sends different query to PostgreSQL on the 2 stores (with different option on "Support on the fly geometry simplification"), but I haven't check to that extent. I shall post again with more observation on this. -- Sent from: http://osgeo-org.1560.x6.nabble.com/GeoServer-User-f3786390.html _______________________________________________ Geoserver-users mailing list Please make sure you read the following two resources before posting to this list: - Earning your support instead of buying it, but Ian Turton: http://www.ianturton.com/talks/foss4g.html#/ - The GeoServer user list posting guidelines: http://geoserver.org/comm/userlist-guidelines.html If you want to request a feature or an improvement, also see this: https://github.com/geoserver/geoserver/wiki/Successfully-requesting-and-integrating-new-features-and-improvements-in-GeoServer Geoserver-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/geoserver-users
