Hi again,
This time I'm using the Query instead of the NodeQuery thank to the wise
advice of Michiel... But I'm still getting unpredictable results:
---
import org.mmbase.bridge.*;
import org.mmbase.storage.search.*;
import java.util.*;
public class PruebaMMBase {
public static void main(String[] args) {
int itemsToShow = 2;
// Set the cloud connection parameters
CloudContext cloudContext =
ContextProvider.getCloudContext("rmi://127.0.0.1:1111/remotecontext");
HashMap credentials = new HashMap();
credentials.put("username", "admin");
credentials.put("password", "admin2k");
// We get connected to the cloud
Cloud cloud = cloudContext.getCloud("mmbase", "name/password",
credentials);
// Create the query to retrieve info from the CMS repository
Query query = cloud.createQuery();
// Define the object types involved in the query
NodeManager url = cloud.getNodeManager("url");
NodeManager tema = cloud.getNodeManager("tema");
// Create the query steps
query.addStep(url);
query.addRelationStep(tema).getNext();
// Add the desired fields
StepField campo_number = query.addField("url.number");
query.addField("url.nombre");
query.addField("url.url");
query.addField("tema.descripcion");
// Establish the sort order
query.addSortOrder(campo_number, SortOrder.ORDER_DESCENDING);
// We set the max number of items to retrieve
query.setMaxNumber(itemsToShow);
// Launch the query against the cloud
List elementList = cloud.getList(query);
System.out.println("-----------------------------------------");
System.out.println(new Date());
System.out.println("-----------------------------------------");
System.out.println("List: " + elementList);
Iterator elementIterator = elementList.iterator();
while (elementIterator.hasNext()) {
// For each node...
Node element = (Node) elementIterator.next();
System.out.println("\t(Node): " + element + "\n");
// We get the desired fields
System.out.println("\t\turl.url: " +
element.getStringValue("url.url"));
System.out.println("\t\turl.nombre: " +
element.getStringValue("url.nombre"));
System.out.println("\t\ttema.descripcion: " +
element.getStringValue("tema.descripcion"));
System.out.println("\t\turl.descripcion (should be empty): " +
element.getStringValue("url.descripcion"));
}
System.out.println("-----------------------------------------");
}
}
The output is as follows (anybody can try it, simply change the NodeManager
and Field names and run):

So the NodeList obtained through cloud.getList(query) seems to contain ONLY
the specified fields, but when I print it the mysterious "url.descripcion"
field appears when it should be blank (because it's not in the query field
list).
The NodeList obtained using NodeQuery instead of Query doesn't contain "not
specifically added fields" either.
Any ideas?
