[ http://issues.apache.org/jira/browse/TOMAHAWK-764?page=comments#action_12446350 ] Michael Heinen commented on TOMAHAWK-764: -----------------------------------------
I am using a4j and it's working like a charm. There are some situations where I think I have to bind the first attribute because it has to be updated in the BB. I have some ajaxlinks which apply a filter on the datatable or remove a filter. This means that the number of elements in the table is dynamic. When I add or remove a filter then I have to set the first attribute back to page 0. The problem is now that the datascroller erased this valueBinding before. (Pls see my first link where I described such a szenario in more detail). I don't see any other alternatives as a valueBinding. Pls correct me if I'm wrong.
