Hi,

If you are using Tasklistner (DelegateTask task) then you can fetch all the candidate groups using

Hope it helps.........

In the Activiti API, taskService.getIdentityLinksForTask(taskId) will return the IdentityLinks associated with the given task.

This can do that!

As for you did not return anything, you should check one thing :

In Activiti's tables, the data that exist in act_id_user and act_id_group must be associated by act_id_membership. Only in this way, the method can return data. Studying these tables is very important.

All of those tables show empty in mine. I have synced these users and groups from keycloak. Does that make any difference?

Yes, I can get an Id if I am in TaskListener. but I am looking for something which I can use outside the TaskListener.

Oh, the method of Activiti API can only handle the data of 23 tables which generated by Activiti.

If your users and groups don't exist in Activiti's tables, you should write method by yourself.

Could you show your diagram or xml code?
