Hello Florian, There did used to be such a chain of events which JMapPane took advantage of, but it was unfortunately dropped some time ago when the feature collection classes were reworked.
The following thread may be helpful: http://osgeo-org.1560.x6.nabble.com/Geotools-8-0-to-9-4-difference-with-SimpleFeatureCollection-and-Map-refresh-td5073829.html#a5073908 Michael On 4 April 2014 01:31, fmd85 <florian-di...@gmx.de> wrote: > Hi, > > I am currently trying to add/delete features on a feature layer and display > them on a JMapFrame.
