Hi I think in this case the problem is related to richfaces. In this page:
http://docs.jboss.org/richfaces/latest_3_3_X/en/devguide/html/a4j_region.html Says this: "... Starting from RichFaces 3.2.0 the <a4j:region> can be used together with iterative components (e.g. <rich:column> or <rich:scrollableDataTable> , etc.). It became possible to re-render a particular row in a table without updating the whole table and without any additional listeners. ..." In JSF 2.0, f:ajax works well with tomahawk, and the code between tomahawk 1.2 and 2.0 is very similar, so I would assume the limitation is related to a4j:region tag. Maybe write the code without wrap the t:outputText inside a a4j:region could work. regards, Leonardo Uribe 2012/10/26 daniel ccss <[email protected]>: > Thanks Michael, > > I want to update the outputtext value that is in the same row of the > selectBooleanCheckbox inside a datatable, yes in RichFaces is easy to do > this, partial update of the datapage, but I'm using Tomahawk JSF 1.2, and > right now we can´t migrate. > > Yes as a matter of fact I put the region around the outputtext as a test, > sorry about that. > > I don´t want to update the hole datatable, if I rerender the hole datatable > using this <a4j:support event="onchange" reRender="*data*"/> it works, the > value of the outputtext is updated on the change event of the > selectBooleanCheckbox because the hole datatable is rerender, but I dont > want to rerender the hole datatable, I only want to update the the > outputtext that is in the same row of the selectBooleanCheckbox that was > checked. > > Really hope you can help me > > > > On Fri, Oct 26, 2012 at 1:07 AM, Michael Heinen <[email protected]>wrote: > >> Do you want to update a complete column or a single cell in the same row? >> Which versions (MyFaces, Richfaces) do you use? >> >> Richfaces doesn't like the forceId attribute in many cases.
