On the previous way I can exclude all the search/build of geometry string
and it could be faster (I don't need to get all those POLYGON etc)
public static TableModel setTableModelFromFeatureCollection() {
final DefaultTableModel model = new DefaultTableModel();
String[] fields;
int iCount;
iCount = featureCollection.getFeatures().size();
FeatureSchema schema = featureCollection.getFeatureSchema();
ArrayList<String> ar = new ArrayList<String>();
String name;
for (int j = 0; j < schema.getAttributeNames().size(); j++) {
name = schema.getAttributeName(j).toString();
ar.add(name);
}
fields = ar.toArray(new String[0]);
// fields = new String[ar.size()];
// fields = ar.toArray(fields);
final String[][] data = new String[iCount][fields.length];
// Feature[] featArray = featureCollection.getFeatures().toArray(
// new Feature[0]);
for (int i = 0; i < featureCollection.size(); i++) {
// < featArray.length; i++) {
Feature feat = featureCollection.getFeatures().get(i);
// featArray[i];
for (int j = 0; j < schema.getAttributeCount(); j++) {
if (feat.getSchema().getAttributeType(j) !=
AttributeType.GEOMETRY) {
data[i][j] = feat.getAttribute(j).toString();
} else {
String geomType =
feat.getGeometry().getClass().getName();
int dotPos = geomType.lastIndexOf(".");
if (dotPos > 0) {
geomType = geomType.substring(dotPos + 1);
}
data[i][j] = geomType.toUpperCase();
}
}
}
model.setDataVector(data, fields);
return model;
}

Anyhow I found an inner OJ way (using LayerTableModel and creating a new
layer from the featurecollection)
Layer layer = new Layer("name", Color.gray, featureCollection,
context.getLayerManager());
LayerTableModel layerMode = new LayerTableModel(layer);
List<Feature> features = resultFC.getFeatures();
layerMode .addAll(features);
AttributeTablePanel panel = new AttributeTablePanel(layerMode ,
true,
context.getWorkbenchContext());
It has to pass through the creatuon of a new Layer, even if not loaded into
the view.
Strangely if I don't add first the featurecollection to the new layer and
than the features (as list) again to the layer, TablePanel will be empty or
I have back an error
