Hi Juan,
As you've discovered, adding/removing relationships require the Cayenne
objects to be registered in an ObjectContext (typically a DataContext).
Generally you'll create and register your objects in an OC using:
DocumentoInventario documentoInventario = objectContext.newObject(
DocumentoIn
I am using Cayenne 4.0.M3.
I want to build an graph of persistent objects using the api for many targets,
but I get the following trace:
Exception in thread "main" java.lang.NullPointerException
at
org.apache.cayenne.CayenneDataObject.addToManyTarget(CayenneDataObject.java:248)
