    Rerender a dynamic datatable with dynamic columns per table

    Darren Smithson Newbie

      Hi all,

      I am having problems trying to rerender a dynamic datatable with dynamic columns, I need to be able to create multiple dynamic tables with each table consisting of 1 row (an object which contains a List) but containing dynamic columns determined by the size of the List in the table row object. I can create the tables and columns succesfully on entry to the page but when I try to add columns to the table via a Modal Panel the table is not being rerendered. The table and columns are built succesfully in the Java code but, like I said, the tables are not being rerendered to display the new number of columns.

      Thanks.

          Are you using reRender your table id on submitting values from your modal panel? make sure you rerender your table after adding column to it.

          Can you post some code snippet?

            HI,

            My code is as follows.....

             

            XHTML....

             

            Binding..

             

             

            ModalPanel which should render the bound table.....

             

             

             

            Java code to build dynamic tables and columns......

             

             

             

            As you can see if I was to define a tableID for rerendering from the modal panel I would have to create the modalPanel also in Java as the tables are dynamnic and therefore I dont know the Ids until runtime.

              As you can see if I was to define a tableID for rerendering from the modal panel I would have to create the modalPanel also in Java as the tables are dynamnic and therefore I dont know the Ids until runtime.

               

              The code works like this....

              THe user inputs values into the modal panel, that is then saved to the DB, when the bound panel is being built it retrieves that info from the DB and creates the dyanmic tables depending upon the size of the list from the DB.

              class NonStdDataTablePanel {

                also the bound panel is being rerendered as the updated number of rows from the List is output via the outputText, which means that problem lies with the datatable alone not being rerendered.
