    seam 2.3 richfaces 4. Datatable with database with edit delete popup

    Bhaskar Dhone Newbie
           

      I am using seam 2.3 and richfaces 4. Using that I am able to show data in datatable which is stored in database. But for edit and delete. I am trying to use example like

        http://showcase.richfaces.org/richfaces/component-sample.jsf?demo=dataTable&sample=dataTableEdit&skin=blueSkyJboss richfaces

      I am unable to do edit with pop up. selected row data is not coming in popup window.

      Please help and suggest how to pass parameter for popup and use that to retrive data for editing .

          Is your render target is not displayed at the time?  Dry rendering a target wrapper around your popup.  Also, you'll likely want to use the domElementAttachment of the popupPanel.

            Hi ,

            Actually I am just trying to impliment live demo sample available for richfaces4 .http://showcase.richfaces.org/richfaces/component-sample.jsf?demo=dataTable&sample=dataTableEdit&skin=blueSkyJboss richfaces  Data table editing sample , with seam and oracle database.

            my render target will displayed once after data is render in editgride.with domElementAttachment of the popupPanel.

              Sorry, missed that.

               

              Do you get any server errors, or any errors in your browser console?

                  Well, given that the showcase example works, I'd start with that.  Slowly introduce changes to align the working showcase with your use case, and see if you can isolate the change that causes it to break.
