Hi,
OK, I did with the Hibernate Tools. It was a pain, to install them properly (I am also using spring). But I found the query. Here it is, for interested people:
| select taskinstance from Domain as dom,
| TaskInstance taskinstance,
| HibernateLongInstance as hibernatelonginstance
| where
| taskinstance.name = 'Change Provider Request'
| and taskinstance.isOpen = true
| and hibernatelonginstance.id =taskinstance.variableInstances.id
| and hibernatelonginstance.name = 'domain'
| and hibernatelonginstance.value.id = dom.id
| and dom.name = :varvalue
|
| varvalue: a domain Name (class Domain has a "name" field)
|
This query searches a TaskInstance that has a "Domain" object assigned.
Take care: it may only work with jbpm >= 3.1.4
The TaskInstance is created like this:
| <task-node name="Task DomBla task">
| <task name="Task DomBla" swimlane="swimlane1">
| <controller>
| <variable name="domain" access="read"></variable>
| <variable name="approve" access="read,write,required"></variable>
| </controller>
| </task>
| <transition name="" to="isApproved"></transition>
| </task-node>
|
This way you may also list some BusinessObjects with their assigned tasks (if you skip the last line of the query)...
When I executed the query in the hibernate console (eclipse) I got a result and eclipse was getting stuck on 100% CPU for quite a while (tested on freebsd, linux and windows). Seems to be a bug in the hibernate console - however - it is beta software.
It may help anyone who neither has a clue about HQL...
Greetings
Harry
