Daniel, I just asked BalusC to add something to OmniFaces that may be able to help. Click URL below and look for *Update specific UIData rows and columns*... You can possibly use this to update the entire row that contains the column that you would like to update.
https://snapshot-omnifaces.rhcloud.com/showcase/utils/Ajax.xhtml Honestly, i don't know if it will work with a JSF 1.2 project, but worse-case scenario, you can view the code, and develop your own code that will globally update datatable rows/columns during or oncomplete of an ajax call. Code details can be found at URL below: issue 82 code<http://code.google.com/p/omnifaces/source/detail?r=47cafb7c9d71160af2c99551e33f207eda081187> Thanks, Howard On Fri, Oct 26, 2012 at 12:35 PM, daniel ccss <danielcc...@gmail.com> wrote: > 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....
