Christophe Lombart commented on JCR-1784:
-----------------------------------------

Done. Thanks for your contribution.  

Do you want to see the latest path in the branch 1.5 ? 
I'm not sure that is critical for the release 1.5.

> On ocm.update transaction, the  Current implementation of DefaultCollectionConverterImpl
recreates the colleciton-element nodes if there is no id field specificaiton.  This is completely
valid for majority of the cases.  But I came across a case where the colleciton element has
a uuid field.  In this case also what is happening with the current implementation is that
it drops all the elements from the old collection-elements and recreates the new ones.  The
major flip side is that now I am left with brand new UUIDs.  I think we should address the
uniqueness characteristics specified through UUID also while mapping colleciton elements.
> I have a patch and a TestCase to verify the same.  I have implemented it only for the
digester.  If people feel the approach is right I will work out an annotation based testcase
as well.  I do not think it is going to fail even with annotations.
