[JBoss jBPM] - Hibernate exception in: at org.jbpm.command.TaskInstanceEndC
by exe
I got an exception from the taskInstanceEnd command.
Is it a bug in the taskInstanceEnd command ?
The stack trace:
Caused by: org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: org.jbpm.taskmgmt.def.Task.events, no session or session was closed

I got simmilar exception when i tried to get taskInstanceVariable (getTaskInstanceCommand without includeAllVariables=true). But there isn't includeAllVariables property in the TaskInstanceEndCommand object.
Thx,
Janos
