Hello,
after upgrading from GeoTools 2.6.6 to 2.7.2, the following code
fails, which was previously working:
mapPane = new JMapPane(new StreamingRenderer(), new DefaultMapContext());
The stack is:
java.lang.NullPointerException
at org.geotools.map.MapContent.listenToMapLayers(MapContent.java:275)
at
org.geotools.map.MapContent.addMapLayerListListener(MapContent.java:225)
at
org.geotools.map.MapContext.addMapLayerListListener(MapContext.java:514)
at org.geotools.swing.JMapPane.doSetMapContext(JMapPane.java:480)
at org.geotools.swing.JMapPane.<init>(JMapPane.java:228)
at
org.argeo.gis.ui.rcp.swing.SwingMapViewer.<init>(SwingMapViewer.java:45)
...
Apparently the problem is in MapContent:
if (listen) {
for (Layer layer : layerList) {
layer.addMapLayerListener(layerListener);
}
} else {
(layerList is null)
Is there now another way to initialize an empty JMapPane ?
Thanks in advance for your help,
Mathieu
