I am facing display problem in SLD. Working on GeoServer 2.8 and OpenLayers 3.
I have one polygon layer in which I am applying SLD, when I view it in my web application polygon number is repeating each times and when I use centroid function it resolves.
But when I update SLD then that "centroid code" part vanishes from entire code.
searching on Google also
code link is: https://jsfiddle.net/5f84nwwj/
Update:updating SLD using Geoexplorer
please check the screenshot
