Hello,
I was wondering if this warning is familiar to any of you...
I have created a layer containing a TemporaryResource (code below) , and it
works correctly, but everytime it needs to be rendered, I get the following
warning:
09-may-2011 12:55:35 org.geotools.map.FeatureLayer getBounds
WARNING: Bounds crs not defined; assuming bounds from schema are correct for
AbstractDataStore.AbstractFeatureLocking(PathType (4))
Is there any way to set the CRS so I dont get the warning all the time?? I have
tried setting CRS in the layer, and also in the featureBuilder :S
IGeoResource newGeoresource =
catalog.createTemporaryResource(pathFeatureType);
FeatureStore fs
=newGeoresource.resolve(FeatureStore.class, null);
FeatureCollection features =
FeatureCollections.newCollection();
features.add(feature);
fs.addFeatures(features);
// Delete old georesources from layer and the
new one
List<IGeoResource>
georesources=pathLayer.getGeoResources();
while(georesources.size()>0){
georesources.remove(georesources.size()-1);
}
pathLayer.getGeoResources().add(newGeoresource);
pathLayer.setBounds(new ReferencedEnvelope(new
Envelope (-180, 180, -90, 90), DefaultGeographicCRS.WGS84));
pathLayer.setCRS(DefaultGeographicCRS.WGS84);
pathLayer.refresh(pathLayer.getBounds(null,DefaultGeographicCRS.WGS84 ));
Thanks,
Joaquín

I found a way around the problem, instead of using layer.setGeoresource(..) for
changing the georesource in the layer, I now remove the old georesource and add
the new one with the following code, and it seems to work correctly :)
layer.getGeoResources().remove(0);
layer.getGeoResources().add(newGeoresource);
cheers,
Joaquín

Asunto: [udig-devel] Dynamic Features Layer Refresh
Hello,
I am having some troube with a vector layer I created which I would like to
modify programatically, and I have wiritten some code that works sometimes, and
some times not. I would appreciate if you could tell me if I am I following the
right approach for doing this..
I have a table of points that changes over the time, and I want to have a layer
representing a line following all the points. For this, I created a Temporary
Resource, and I added it as a layer:
// Create path layer
List<ILayer> layers = new ArrayList<ILayer>();
IGeoResource tempResource =
catalog.createTemporaryResource(pathFeatureType);
Layer layer= layerFactory.createLayer(tempResource);
layer.setName(GEORESOURCE_PATH_REAL);
layers.add(layer);
map.sendCommandASync(new AddLayersCommand(layers));
Then, every time some one inserts a point in the table, I would like to
recalculate the feature (the line) in the temporary resource and redraw it.
Coordinate[] coords= new
Coordinate[positionsCoords.size()];
....... calculate new line.........
LineString line =
geometryFactory.createLineString(coords);
// Create Feature containing the line string
// add the attributes in order
featureBuilder.add(line);
featureBuilder.add(1);
featureBuilder.add("Path");
// build the feature
SimpleFeature feature =
featureBuilder.buildFeature("Path");
// Remove all features from igeoresource and
add the new one
IGeoResource georesource =
pathLayer.getGeoResource();
FeatureStore fs = null;
fs = georesource.resolve(FeatureStore.class,
null);
fs.removeFeatures(Filter.INCLUDE);
FeatureCollection features =
FeatureCollections.newCollection();
features.add(feature);
fs.addFeatures(features);
pathLayer.setGeoResource(georesource);
}
This piece of code works sometimes, and I can see the new line drawn whenever I
execute this (in a command or action), but most time the line is not redrawn. I
have tried using layer.refresh(bounds), but It does not fix it. Is there any
other way to force the redraw of the layer? I can debug and see that the
feature was correcly updated in the georesource...
Is this the right approach for doing this?? or maybe there are some other ways
to do it?
Thanks!
