Surely this is not intended! Entity.getProperty() gives exactly the
same result, null, if there is no property, there is a property set to
null or there is an empty Collection!
DatastoreService datastore =
DatastoreServiceFactory.getDatastoreService();
Key key = KeyFactory.createKey("testKind", "testKey");
Entity e = new Entity(key);
e.setProperty("null", null);
e.setProperty("emptylist", new ArrayList<String>());
datastore.put(e);
try {
Entity e2 = datastore.get(key);
System.out.println(e2.getProperty("null")==null);
System.out.println(e2.getProperty("emptylist")==null);
System.out.println(e2.getProperty("doesNotExist")==null);
} catch (EntityNotFoundException exc) {
exc.printStackTrace();
}
Result:
true
true
true
At the very least an empty list should be saved as an empty list no?
