Hello,
I wonder if this error sounds familiar to you.. I have been getting it often
when rendering WFS layers in uDig, and I cannot find anything on google.
Sometimes It happens, and sometimes not, it is intermitent, but when it
happens, at least one of the wfs layers is not rendered and I have to click
the refresh button to get it rendered. As a workaround I can programatically
refresh all the layers once the last one is loaded (I check this with the
layerInterceptor), but It would be good to know why is really happening.
I have started my application from the RCP sample, so in the mapviewer class I
add 10 WFS layers as follows. (If I just add one layer it does not happen
usually, I guess the error comes because I am adding serveral layers, is there
any better way to do this?):
MapView.java
.........
// create a new empty map
// if you are going to add layers do so now
// prior to adding to the mapviewer
//
map = (Map) ProjectFactory.eINSTANCE.createMap();
LayersUtil.AddLayersToMap(map);
mapviewer.setMap(map);
.........
LayersUtil.java:
public static void AddLayersToMap(final Map map) {
List<ILayer> layers = createMapLayers();
map.sendCommandASync(new AddLayersCommand(layers));
}
public static void createMapLayers(){
List<ILayer> layers = new ArrayList<ILayer>();
URL url = new URL(MAPSERVER_GETCAPABILITIES_WFS);
IServer handle = catalog.acquire(url, null);
if (handle != null) {
List<IGeoResource> resources = (List<IGeoResource>)
handle.resources(new NullProgressMonitor());
for (IGeoResource resource : resources) {
String
layerId=resource.getIdentifier().toString();
if
(layerId.equals(MAPSERVER_GETCAPABILITIES_WFS + "#"+GEORESOURCE_POSITION_REAL)
) {
Layer
layer=layerFactory.createLayer(resource);
layers.add(layer);
}
else if (layerId.equals(.....
....
}
}
}
This is what I get:
