How to update specific row in Primefaces datatable

Question

Primefaces 3.5, Mojarra 2.1.14. This is my PF datatable, it contains one non-editable boolean column named \'automatic\', and editable \'label\' column:

Answer 1

You p:ajax tag is inside p:dataTable no in some specific row or column, so you cent so easy update some relative component id. You can with help of RequestContext update specific component in cell. So, remove update from p:ajax and add this to your onEditLabel method:

RequestContext.getCurrentInstance().update(
  s.getClientId(FacesContext.getCurrentInstance()) +
  ":" + event.getRowIndex() +
  ":isAutomatic"
);

As you can see, id of component inside cell has row number before id you assigned.
