Hello, I am seeing a similar problem with my geotools application. I create a map display with several layers created from shapefiles and additional "direct layers" for a scalebar, title, and legend. The styles of two of the shapefile layers are updated based on user action. For example, the user can specify a city name which causes the program to update the styles of the city polygon feature and point features that fall inside the city polygon.
As shown in the attached two screen shots image1 <http://s8.postimg.org/nrf8kh68l/image1.png> and image2 <http://s10.postimg.org/tv7gncnop/image2.png> , some of the shapefile layers were not rendered properly. The problem manifests itself somewhat randomly. I've tried updating the styles in a background thread as shown here but that did not solve the issue. // this snippit is called with the GUI app's main execution thread Task mapUpdater = new Task() { @Override protected Object call() throws Exception { // these three methods call setStyle on a layer handler.updateSelectedPoi(setPoi); handler.updateSelectedZipCodes(setZip); handler.updateSelectedRegions(setRegion); return new Boolean(true); } }; Thread th = new Thread(mapUpdater); th.setDaemon(true); th.start(); I am using geotools 10.3, JDK8 and javafx 2.2. The geotools map pane is an embedded Swing Object. I have reproduced the problem in a Swing environment as well. Any suggestions are greatly appreciated, Hal -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Problems-to-rendering-the-map-using-JMapPane-tp5020512p5099050.html Sent from the geotools-gt2-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
