-------------------------------------------------------
Key: CAY-1195
URL: https://issues.apache.org/cayenne/browse/CAY-1195
Project: Cayenne
Issue Type: Bug
Components: Cayenne Core Library
Affects Versions: 3.0M6
Environment: ROP
Reporter: Marcin Skladaniec
the many to many relationship cannot be accessed from the other side that it
was set.
test case (sorry not as a patch, to much other modifications to be able to
create a diff)
public void testCAY1195() throws Exception {
deleteTestData();
ClientMtTable4 parentMt = context.newObject(ClientMtTable4.class);
ClientMtTable5 childMt5 = context2.newObject(ClientMtTable5.class); //
I added context2 to the RemoteCayenneCase. it is created the same way as the
original context
assertEquals(0,parentMt.getTable5s().size());
assertEquals(0,childMt5.getTable4s().size());
ClientMtTable4 parentMtCopy =
(ClientMtTable4)context2.localObject(parentMt.getObjectId(), null);
childMt5.addToTable4s(parentMtCopy);
assertEquals(1,parentMtCopy.getTable5s().size());
assertEquals(1,childMt5.getTable4s().size());
}
