Null pointer exception at org.apache.cayenne.CayenneDataObject.addToManyTarget(CayenneDataObject.java:278)
Hi,
I really need help to find out what is happening here. I was adding an
object to a parent object. Below you will find all the logging output and
attached you'll also find my cayenne.xml along with the other xml files from
my project.
Thanks in advance for your help!

Re: Null pointer exception at org.apache.cayenne.CayenneDataObject.addToManyTarget(CayenneDataObject.java:278)
Posted by Ronald Zúñiga <ro...@gmail.com>.
This is the code that generated the error:
public static void main(String[] args) {
DataContext context = DataContext.createDataContext();
Contacto contacto = (Contacto)context.newObject(Contacto.class);
contacto.setCedula("603330034");
contacto.setNombre("Ronald Zúñiga Orozco");
contacto.setTelefonos("88235384");
Cliente cliente = (Cliente) context.newObject(Cliente.class);
cliente.setCedula("123456");
cliente.setNombre("Shell");
cliente.addToContactos(contacto);
context.commitChanges();
}
Thanks for your help!
Ronald.

Re: Null pointer exception at org.apache.cayenne.CayenneDataObject.addToManyTarget(CayenneDataObject.java:278)
Posted by Andrey Razumovsky <ra...@gmail.com>.
Object is unregistered (transient) if it is created by constructor. To get a
registered object, use ObjectContext.newObject(...) or
ObjectContext.registerNewObject(..) on unregistered object.
That's only a guess, can you show the code from TestMain causing the
exception?

Re: Null pointer exception at org.apache.cayenne.CayenneDataObject.addToManyTarget(CayenneDataObject.java:278)
Posted by Ronald Zúñiga <ro...@gmail.com>.
Hi Andrey,
I downloaded the Cayenne
2.0.4<http://www.apache.org/dyn/closer.cgi/cayenne/cayenne-2.0.4.tar.gz>from
the Latest Stable Releases section.
What you mean by not registered in context? Where can I do that? I'm
relatively new to cayenne and I tried to make it work but the error is not
informative at all.
Thanks!
Ronald

Posted by Andrey Razumovsky <ra...@gmail.com>.
Hi Ronald!
What version of Cayenne are you using? Cannot say for sure without the code
causing the exception, but I think I suffered something similiar when I
tried to create a relationship between transient and committed object
(e.g. Cliente object is commited and Contacto you add is transient and
not registered in context).
