Re: object regsitered in a different DataContext

Thank u for your help. But I'm sure I use only one static DataContext. Could be that the problem ?

public class CayenneConnection {

  public static DataContext dataContext;
.....

Basically, persona is from a different DataContext, so CayenneConnection.dataContext is having trouble deleting it. You can use

CayenneConnection.dataContext.localObjects(Collections.singletonList(persona))

to get a copy of the object local to this DataContext which it should be possible to delete.

Hello boys
  
I'm a newbie, and I'd like to simply delete a DataOject in Cayenne. I have tried this code:
 
         PersonaFisica persona = (PersonaFisica) ( (DOTableModel)  jPanelTable.table.getModel()).getDataObject(selRows[0]);
         CayenneConnection.dataContext.deleteObject(persona);  // here persona is not null
         CayenneConnection.dataContext.commitChanges();
 .....
 
 
But I got the following error:
 
 
org.objectstyle.cayenne.CayenneRuntimeException: [v.1.2M8 November 24005]  Attempt to delete object regsitered in a different DataContext
 
 
What does it mean ? Could someone help me please ? Any advices will be useful.
 
For connection I use a class like this:
 
 
public class CayenneConnection {
 
   public static DataContext dataContext;
   public static DataView dataView;
   public static Configuration conf;
 
......
 
 
   /**
    * connect
    */
   public static void connect() {
     init();
     try {
       dataContext = DataContext.createDataContext();
     }
     catch (Exception ex) {
       ex.printStackTrace();
 
       JOptionPane.showMessageDialog(
           null,
           ex.getMessage(),
           "Connection Error",
           JOptionPane.ERROR_MESSAGE);
       return;
     }
   }
 
   /**
    * loadDataView
    */
   public static void loadConfig() {
     dataView = new DataView();
     dataView.setEntityResolver(dataContext.getEntityResolver());
     try {
       conf.loadDataView(dataView);
     }
     catch (IOException ioex) {
       ioex.printStackTrace();
       throw new CayenneRuntimeException("Error loading DataView", ioex);
     }
   }
 
   /**
    * init
    */
   public static void init() {
     DataSource dataSource1 = null;
     DataSource dataSource2 = null;
     try {
       dataSource1 = new PoolManager(Config.defaultFirebirdDriver,
                                     Config.defaultFirebirdUrlPrefix +  Config.firebirdUrl + Config.defaultDbAnagrafica,
                                     1,
                                     5,
                                     Config.firebirdUser,
                                     Config.firebirdPassword);
 
       dataSource2 = new PoolManager(Config.defaultFirebirdDriver,
                                     Config.defaultFirebirdUrlPrefix +  Config.firebirdUrl + Config.defaultDbPaghe,
                                     1,
                                     5,
                                     Config.firebirdUser,
                                    Config.firebirdPassword);
     }
     catch (SQLException ex) {
     }
     conf = Configuration.getSharedConfiguration();
     DataDomain domain = conf2.getDomain();
     DataNode node1 = domain.getNode("MyDomainNode");
     DataNode node2 = domain.getNode("MyDomainNode2");
     node1.setDataSource(dataSource1);
     node2.setDataSource(dataSource2);
   }
 
}
 
Thank u in advance and greetings from Italy.
