Subject [jira] Resolved: (JCR-1784) OCM:The UUID of the collection elements changes on update.

]

Christophe Lombart resolved JCR-1784.
-------------------------------------

    Resolution: Fixed

The patch has been applied. thanks and well done ! it was a nice bug :-) 
I didn't modify the class AbstractMapperImpl. For me, this modification is not necessary.

I also added unit tests for the annotation support. 

Let me know if something is wrong.

> 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.
