Re: [udig-devel] Upgrade uDig 1.1.1 with GeoTools 2.5

[Rodolphe QUEMERAIS <rodolphe.quemerais@xxxxxxxxx>]

Thanks for the answer.
It's just fine to me.
For the question C, I found out the answer by myself ^^
For those who will read this, here is my code:

		public void modifyFeatures() throws IOException {
			
                        DefaultTransaction transaction = new
DefaultTransaction("test");
			String featureTypeName = feature.getFeatureType().getTypeName();
			try {
			FeatureStore store = (FeatureStore)
dataStore.getFeatureSource(featureTypeName);
			
			store.setTransaction( transaction );
						
			FilterFactory ff = FilterFactoryFinder.createFilterFactory();
			FidFilter filter2 = ff.createFidFilter();
			filter2.addFid(feature.getID());
			
			FeatureType featureType = store.getSchema();
			AttributeType att = featureType.getAttributeType("Type");
			
				store.modifyFeatures(att, "WebCam", filter2);
				transaction.commit();
				System.out.println("Transaction done");
			} catch (Exception e) {
				transaction.rollback();
				System.out.println("Rollback done");
				
			} finally {
				transaction.close();
			}

		}
// This code works fine.... for changing a String like attribute

Thanks a lot for the answer.
