| 15:22:17,500 ERROR [Task] Error initializing task page:
java.lang.ClassCastException: org.hibernate.collection.PersistentList
|
while executing this code using the command interface:
| public Object execute(JbpmContext jbpmContext) throws Exception {
|
| TaskInstance taskInstance =
jbpmContext.getTaskInstance(this.taskInstanceId);
|
| List comments = taskInstance.getComments();
|
| return comments;
| }
This is a very simple code, and by the output i supose that the problem comes
from hibernate, that i don't have knowledge of it.
Any ideia that it could be?
Thanks
