-----------------------------------

the problem does not exist when the button resides in columns outside of the footer-facet.

> when adding a a4j:commandButton inside a rich:databables footer-facet, the corresponding action will be invoked twice while the process action phase.
> The problem only occurs, when the commandButton 'process'es the datatable itself.
