Hi,
at the moment I am trying to use OCL queries instead of traversing the
whole model to find some objects. This works great, until I delete some
object. Then my query fails with:
org.eclipse.emf.cdo.util.ObjectNotFoundException: Object OID154 not
found in branch 0 at * (test and stacktrace below).
An OCL query like "Product1.allInstances()" should give me all instances
which are contained in the resource at the moment and not all instances
ever created. Do I have this right?
Regards,
Nils
This exception is reproducible by the following test method in
org.eclipse.emf.cdo.tests.OCLQueryTest
public void testDeletedObject() throws Exception
{
CDOQuery query = transaction.createQuery("ocl",
"Product1.allInstances()", getModel1Package().getProduct1(), true);
List<Product1> products = query.getResult(Product1.class);
int numOfProducts = products.size();
resource.getContents().add(0, getModel1Factory().createProduct1());
transaction.commit();
resource.getContents().remove(0);
transaction.commit();
query = transaction.createQuery("ocl", "Product1.allInstances()",
getModel1Package().getProduct1(), true);
products = query.getResult(Product1.class);
assertEquals(numOfProducts, products.size());
}
leeds to:

Hi Nils,
I've fixed this in:
Bug 342595: OCLQueryHandler does not ignore old revisions
https://bugs.eclipse.org/bugs/show_bug.cgi?id=342595
Cheers
