Thanks Jairo for the reply and hints.
I'm pretty sure I've moved all code that 1) creates and adds the JMapPane
the JavaFX GUI node, 2) adds layers to my JMapPane and, 3) updates the
styles of the map layer to inside blocks such as:
javafx.application.Platform.runLater(new Runnable() {
public void run() {
.
}
});
So far no change in rendering. However, I did notice that adding a short
sleep after calling setStyle seems to eliminate the problem:
mylayer.setStyle(mystyle);
try {
Thread.sleep(100);
} catch (InterruptedException e) {
}

JMapPane
Probably a conflict with threads that are triggered by internally-GeoTools
in my case replace the addLayer by addLayers with my layers in mapcontent
and worked
deducting the threads of your code finalized the process of thread addLayer
triggered by the GeoTools.

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
