In human task, dynamically assign group doesn't work

Question

Oracle SOA 11.1.1.4
My bpel process invokes a human task.
On the human task Assignment tab, I assigned 3 users (by name), 1 group (by expression).
The group is configured in LDAP
When I tested the bpel process, I entered the group and other data required.
From the worklist app, I see the task listed. It is assigned to the 3 users, but not the dynamically passed-in group.
From the Audit trail, I saw all data I entered (include the group). Everything seems correct, but I still can’t make the dynamically-pass-group work.
If I assign the group by name in human task, it works fine.
The problem is: dynamically assign group doesn't work.
Please kindly advice.

Answer 1

Yes, it is possible assign a group as participant of some human task, passing the group name as parameter.
I have tested just now.
It works pretty well in SOA 11.1.1.4 (BPEL or BPM).
Make sure add a data parameter in your human task definition and pass a valid group name to it.
At the Assignment tab, in the participants' list, add a group, data type by expression, and set the value to the right xpath expression to the corresponding parameter.
For example: /task:task/task:payload/task:group
If it is not working look the SOA log files, probably you'll find some information about the error there. Maybe there is some problem with your jazn.com configuration.
You can also test if there is something wrong related to the group name, trying to transfer some task to the same group by the worklist.
