[udig-devel] adding a layer from the memory store in rc10

[Adrian Custer <acuster@xxxxxxxxx>]

Hey all,

Code that used to work now breaks and I'm not sure why although I have
discovered where. After creating a memory layer I'd like to add it to
the map. The layer builds fine and I can manually add it to the map
correctly. The code which works to create the Layer is:

IGeoResource newIGR = CatalogPlugin.getDefault().getLocalCatalog().
                              createTemporaryResource( myBufferFT );

FeatureStore newFS = null;
if (newIGR.canResolve(FeatureStore.class)) {
   try {
   			
   		newFS = newIGR.resolve(FeatureStore.class, monitor);;
   			
   } catch (Exception e) {
   	System.err.println(
   	   "Resolving the IGeoResource failed with exception " + e);
  	// TODO: re-emit the exception, bail from the operation.
   }
}

final Iterator<Feature> iter = Arrays.asList(myBufferF).iterator();

newFS.addFeatures( (FeatureReader) new FeatureReader(){
  public boolean hasNext(){  return iter.hasNext(); }
  public Feature next() { return iter.next(); }
  // TODO: what should this be?
  public void close() { ; }
  public void remove() {throw new UnsupportedOperationException();}
  public FeatureType getFeatureType(){return this.getFeatureType();}
  }
);
    
// WHY? Creating the Layer is what adds it to the catalog!?
LayerFactoryImpl myLF = LayerFactoryImpl.create();


However the next line, fails:
myLF.createLayer(newIGR);

it fails in line 451 of LayerFactoryImpl which is:
ColourScheme colourScheme = getMap().getColourScheme();

because the getMap() returns null and so the .getColourScheme() doesn't
work which leads to the catch block at line 181 of OpAction.class.

Any ideas what I should be doing?
