Hi,
I tried to “unset” an owner of a UserTask this way:
taskService.setOwner(taskId, null);
and got the exception
org.camunda.bpm.engine.ProcessEngineException: userId and groupId cannot both be null
at org.camunda.bpm.engine.impl.cmd.AddIdentityLinkCmd.validateParams(AddIdentityLinkCmd.java:66)
Just want to ask if this is by design and if it is not allowed to set the owner to null once it was set or if I missed how to unset the owner.
Thanks
Franz
