Hi again Martin. I want to access the data from my custom dataScroller Renderer Class. public class MaeHtmlDataScrollerRenderer extends HtmlDataScrollerRenderer
This means even if I use the binding property for dataTable, I am stuck. Cause of the protected methods I cannot get the data out. What do you mean by set the value to a data-model? As in a new property to the custom dataScroller?
