Thanks Mike, yes that is what I have, it was a copy/paste error: *<a4j:support event="onchange" reRender="textVehicleName"/>*
Yes I have done that with richfaces is very simple, but this project is old, and right now I don´t have time to migrate, so.... There is not a way for accomplish this, update a single column of a t:datatable with ajax, using JSF 1.2 and Tomahawk?? I have to refresh the hoooole datatable??? Hope someone has done this, thanks!
