    Retrieveing a var when the class changed

    François LE QUEMENER Newbie

      Hi,
      I'm storing a variable in my process instance. I discovered that if I change a class which is used in this var, jBPM is unable to retrieve the process instance so I can't use the old process instances.
      Is there a way to make possible to change the classes, and the workflow would be able to retrieve the old ones? (I am especially thinking about new versions of my program)

      Thanks
