Hi, We are currently converting our application from jbpm3 to jbpm4. In the old version, we extended the TaskInstance with some extra properties by registring our own TaskFactory in the jbpm config file and extending the hibernate mapping for TaskInstance. How is this possible in jbpm4? Is there something like a TaskFactory we can overrule in the configs?
