Thanks Leonardo, Im not using rich faces, and I'm using tomahawk with JSF 1.2 so f:ajax do not exists, I will migrate to JSF 2, but right now I cant, so is a way to accomplish this columna partial update inside a datatable without rendering the hole t:datatable?
For ajax we are using: <%@ taglib uri="https://ajax4jsf.dev.java.net/ajax"; prefix="a4j"%> Thanks hope someone knows a way P.D: I already erase the a4j:region and it doesn´t work On Fri, Oct 26, 2012 at 9:53 AM, Leonardo Uribe <lu4...@gmail.com> wrote: > Hi > > I think in this case the problem is related to richfaces.
