      Description

      FULL PRODUCT VERSION :
      java version "1.6.0"
      Java(TM) SE Runtime Environment (build 1.6.0-b105)
      Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode, sharing)


      ADDITIONAL OS VERSION INFORMATION :
      Ubuntu 7.04

      A DESCRIPTION OF THE PROBLEM :
      I made a Table with a fixed first row with a rowHeader(JTable) and a JTable for the rest iof the colums as described in o'reillys Java Swing 2nd edition.

      without rowsorting actually enabled it just wored fine.

      When I do sort a row and update (insert a row) in the underlying tablemodel I get these error.

      It seems that the row sorter gets notified from both JTables.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      compile and run.
      1. insert a row
      2. selecting a row to sort (mouseclick on the column header)
      3. inserting an other row
      error occured!


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      a sorted table
