[jboss-user] [JBoss jBPM] - Retrieveing a var when the class changed

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 View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4231981#...
