    Datascroller and editable datatable

    Benjamin Fayle Newbie

      I have a dataTable that is editable. When the user enters data and clicks the dataScroller the data entered is lost. How do I get the dataScroller to update the model prior to the data scrolling changing pages?

          AjaxSingle = false should resolve this.

            Thanks - the documentation is a bit sparse on many of the attributes.

              Did using the AJaxSingle=false work for you? I tried it to no avali.

                ekinsey, all the customers that was trying this case was succesfull with ajaxSingle="false".

                Explain more carefully your case. Code snippets and environment info will be helpfull.

                  Hi iLya,

                  I've attached my sample code. When I enter text into the inputText boxes and page to another page using the datascroller the data is missing from the inputText boxes when I navigate back to the page. I help that you can provide is greatly appreciated. Also, please forward any working code that you may have.

                  Best regards,
                  -E
