Description Alex Lagarde CLA 2011-07-15 05:39:06 EDT 
As it has been discussed on the forum : http://www.eclipse.org/forums/index.php/t/217079/

it is possible to lock detached elements using a CDOTransactionHandler1.

JUnit tests should be written to ensure that this usecase works correctly

Fix

It turns out that TRANSIENT (detached) objects can not be locked through CDOObject.cdoXyzLock().lock() because they have no view pointer anymore. This situation is detected and an IllegalStateException thrown with the hint to cll CDOView.lockObjects() instead.

Test is in org.eclipse.emf.cdo.tests.LockingManagerTest.testLockDetached()
