Hi Noppong,

I'm not quite sure, if I got your point, but I assume that it would be a solution, if you just create a column in the table, with an overlay as child, that itself holds the textbox. The value of the textbox than can just be coming from the datTable variable, just as for any other filed in the table. It might look somehow like this:

<wec:dataTable id="..  var="dataTableVar">



       <wec:overlay id="overlay" ...>

          <wec:inputText id="... value="#{dataTableVar.textToBeChanged}" />




You might even have the overlay with its included Textbox in the same column, as your image, if you like to.
