    method modify and filter

    Eugene Bessel Newbie

      since I implemented the method modify in my DataTableModel, the filtermethod doesn't work.



      first of all I implemented the filterMethod like in



      then I implemented the DataModel and method modify like


      public void modify(List<FilterField> arg0, List<SortField2> sortFields) {



      now the application doesnt go into my filterMethod.


      is the new method modify responsible for this behavior??


      can I delegate the filtercall to my filterMethod??


      thank you

          If you use ExtendedDataModel which implements Modifiable as value of DataTable you should manage filtering and sorting yourself.

            Hallo Konstantin.


            you are right. when I remove the method modify and when my column is not implemented the interface Modifiable then the framework sort the datavalues by itself.


            it is ok.


            The Component ExtendedDataTable has a very usefull feature: "groupBy". The disadvantage of ExtendedDataTable is that it is very very slow.


            So I try to implement simple DataTable and if I know which column should be sorted, then I can go throw the sorted column and when the value is changed then I add new empty row .

            On the page the user can see goups of dataValue.


            do you know what I mean??


            For this purpose I tried to implement the method modify.

            The first problem I still dont know which column should be sorted.

            The second the framework dont want to sort the data. I thought that I can call some method from framework and provide my Data to sort. But which Method??
