Kaleo workflow assign-to a list of users

[Enrico Maria Rossi, módosítva 11 év-val korábban]

Hi,
with Kaleo Workflow is it possible in My Worflow Tsks page assign-to a list of users?, I see, i can assign-to only one user. Thanks.

Regards,

Enrico

You need to tweak the workflow definition file to assign the task to specific roles.

then you can map set of users into that roles. So, Tasks will be assigned to all the users mapped with specif role

Hi Gnaniyar Zubair,
thanks, but I did it. I attached my xml file.
My case is Sequential according to roles. 3 step to publish a WebContent.
Only the role "Redattore KBMS Super" can reject or assign to a list (2-3-4) of users or publish a WecContent in every moment (my expected goal).
The role "Redattore KBMS Basic" can assign a task to a list (2-3-4) of users and can approve for next step or reject, but he can't publish a WebContent (my expected goal).
In the select that appear on My Workflow Tasks (newscreenshot) page how can I assign a task to a 2-3-4 of users. I see that I can select only one user from extinsting users. From xml i don't manage it. Can you help me? Thanks and sorry if I' didn't explaine well my problem.

I have to modify the Workflow classes's methods, because in these classes there are methods only for assign a task to one user (expected List<User>). Example:

If you see workflow_task_action.jsp below, you see that you can assign a task to only one user:

Solution????

[Gauri Bansode, módosítva 10 év-val korábban]

Hi Enrico Maria Rossi,

Have you got the solution? I need same requirement, In My Workflow Task portlet instead of only one user (in Drop Down box) I want to assign a workflow task to some List of users having Same Role and then make the task Approved if at least 2 users of them approve that task. It would be great if you share your solution here.
Thanks in advance.

Regards,
Gauri
