Ok, that makes sense.
But doing:

                UndoableMapCommand createAddFeatureCommand = EditCommandFactory
                        .getInstance().createAddFeatureCommand(feature, layer);
                map.sendCommandASync(createAddFeatureCommand);
                // and put it inside the map
                Feature newFeatureAdded = ((AddFeatureCommand)
createAddFeatureCommand)
                        .getNewFeature();

I get a:

java.lang.NullPointerException

I create a full geometry, but I don't know what you mean by singularity.

Shapefile.

Thanks,
