fb:identify doesn't work with repeater of repeaters
---------------------------------------------------

         Key: COCOON-1813
         URL: http://issues.apache.org/jira/browse/COCOON-1813
     Project: Cocoon
        Type: Bug
  Components: Blocks: Forms  
    Versions: 2.1.8    
    Reporter: Eric Meyer


I have a repeater where each row contains a different repeater (concretely a repeater of "tabs"
where each row contains a repeater of "modules"). I used the tasktree example (http://cocoon.zones.apache.org/demos/21branch/samples/blocks/forms/do-taskTree.flow)
for a sample structure to get me started.

I can see that the fb:identity bindings for both the outer and inner repeaters are being loaded
successfully. However reordering inner or outer repeater elements does not result in any of
the collection items being reordered in the underlying object model.

If i remove my fb:identity bindings, then new objects are successfully created each time the
form is saved (and the old ones are discarded). This is not ideal, as the objects are persistent
(mapped using Hibernate). I have a work-around, but it's not pretty.

The use of repeaters inside repeaters is pretty rare, so I think I just stumbled into a dusty
corner. I'd be happy to collaborate on a fix.

Regards,
Eric
