      Hello All,
      I get the nullpointer exception when i dynamically assign the grouping column.



      java.lang.NullPointerException

      I am using 3.3.1 GA, I am also applying sortColumn and sortingOrder Dynamically.

      Please suggest the solution , FYI I gone throught the ExtendedDataTable class and i found the following if condition 
      is creating the problem
      if   (groupingColumn.getSortOrder().equals(Ordering.UNSORTED)) {

      		groupingColumn.setSortOrder(Ordering.ASCENDING);

      }


       

      Thanks
