    Flush during cascade is dangerous Exception

    Thiagu Mariappan Novice

      hi every one

      this is my project environment

      jboss seam: 2.1.0.A1
      jboss server:4.2.2.GA

      I my page I display the huge amount of data displayed in the form of table.
      I fetch those data by using EJP 3 by using PersistenceContext.
      When more than one person try to access that particular page at a time
      I got following exception
