the org.jbpm.taskmgmt.TaskInstanceFactory provides the possibility to create a TaskInstance (docs: http://docs.jboss.com/jbpm/v3/userguide/taskmanagement.html#customizingtaskinstances). But that is no interface, that I can implement. To extend the TaskInstance is no possibility for me because of persistence reasons.
is there any other possibility like node.types.xml (doc: http://docs.jboss.com/jbpm/v3/userguide/configuration.html#nodetypesconfigurationfile)
(I have the same problem with the ProcessInstance)
Thank you!!
