Hi Flavio.
I didn't test your code, but maybe you are missing
mapContext.beginAtomicEvent() and mapContext.endAtomicEvent().
I have something like this, and it works:
mc.getMapContext().beginAtomicEvent();
final FLayers mcLayers = mc.getMapContext().getLayers();
FLayers newGroup =
mc.getMapContext().getNewGroupLayer(mcLayers);
newGroup.setProjection(mc.getProjection());
newGroup.setName(nom);
for (int i=0; i < shpLayers.size(); i++) {
ShpLegend aux = shpLayers.get(i);
FLyrVect lyr = (FLyrVect) LayerFactory.createLayer(nom +
aux.shpName, "gvSIG shp driver",
new File(dirShps.getPath() +
File.separator + nom+
aux.shpName + ".shp"),
mc.getProjection());
newGroup.addLayer(lyr);
loadLegend(lyr, aux.gvlName);
}
mcLayers.addLayer(newGroup);
mcLayers.moveTo(0, mcLayers.getLayersCount()-1);
mc.getMapContext().endAtomicEvent();
Hope it helps.
Best regards.
