Target pointed Attribute for of AjaxStatus component with id revaluation-process-status not is AjaxContainer
Just a guess but the id for the status attribute seems like it has to be for a a4j:region component.
Do you really need the status attribute for the command link? There is already a a4j:status assigned to that a4j:region.
Cuirous because I've never used the "status" attribute myself before.
I tried that and I get the same exception...
