many to many and objects in different context
---------------------------------------------
Key: CAY-748
URL: https://issues.apache.org/cayenne/browse/CAY-748
Project: Cayenne
Issue Type: Bug
Components: Cayenne Core Library
Affects Versions: 3.0
Environment: remote persistence
Reporter: Marcin Skladaniec
If there exists a flattened many to many relationship Project - Employee:
CayenneContext context = ContextManager.getNewContext()
CayenneContext context2 = ContextManager.getNewContext();
List projects = context.performQuery(new SelectQuery(Project.class));
List employees= context2.performQuery(new SelectQuery(Employee.class));
Project p = (Project)projects.get(0);
Employee e = (Employee)employees.get(0);
logger.info(p.getEmployees().size()); => gives 0
logger.info(e.getProjects() .size()); => gives 0
e.addToProjects(p);
logger.info(p.getEmployees().size()); => gives 1
logger.info(e.getProjects() .size()); => gives 2 !!
Adding objects from different context causes the relationship to be doubled at
one end.
I'm sorry I have no time at the moment to investigate this issue further.
