Thanks Howard!!!!, and everyone But the point is that I used *JSF 1.2 with tomahawk*, not prime with JSF 2.0, is an old app that I have to update for fix a problem with the updating fields of that datatable, and right now I do not have time to migrate, in the future I will, but I have to resolve this with the technology that the app uses,
So here is the question does anyone, in some point of your life, accomplished this with this technology: 1- JSF 1.2 2- Tomahawk Framework 3- Using for ajax this: <%@ taglib uri="https://ajax4jsf.dev.java.net/ajax" prefix="a4j"%> Thanks!!! and again thanks great discussion group!
