The problem is in the second part: div.visible-xs
https://github.com/richfaces/richfaces/blob/RF-12901-showcase/examples/bo...
If we remove it, everything starts to work okay, so the problem must be in
attributesRepeat.xhtml
https://github.com/richfaces/richfaces/blob/RF-12901-showcase/examples/bo...
that included templates use another approach then the ones on top:
attributesDataTable.xhtml
https://github.com/richfaces/richfaces/blob/RF-12901-showcase/examples/bo...
I think the problem is with ui:repeat and as the stacktrace suggests.
I propose to minimize a sample for reproduction and report it in RF issue
tracker.
