rich:orderingList doesn't update the correct instance when 
-----------------------------------------------------------

                 Key: RF-3702
                 URL: http://jira.jboss.com/jira/browse/RF-3702
             Project: RichFaces
          Issue Type: Bug
    Affects Versions: 3.2.0
         Environment: facelets 1.1.14
            Reporter: Zied Hamdi

The 'selection' attribute of 'rich:orederingList' doesn't update the binded object when in a loop (ui:repeat, a4j:repeat, h:dataTable), but the first element instead. 

See the log output that demonstrates the problem:
Initialized ListHolder with : [my, first]
Initialized ListHolder with : [my, last]
Initialized ListHolder with : [my, everything]
selected set on '[my, first]'
Button clicked on '[my, last]'

----------------------------------------- workaround attempt -----------------------------
I've tried to do a binding on each row but it doesn't work too: I have an error as if ui:repeat was performed at compile time, but I'm almost sure it is a render-time tag (it doesn't work with a h:dataTable too)
