    StaleObjectStateException problem

    sean liu Newbie

      when the program invoked "org.jbpm.db.TaskMgmtSession.findPooledTaskInstances", the StaleObjectStateException was throwed.I cant figure out why this exception was thrown in jbpm, so want to get some ideas from here.
      Thanks in advice.
