Hi Roman,
I found my mistake by showing sql log for authorization query.
It is important to add a RESOURCE_ID in Authorization otherwise it would not work ( maybe set a NotNull constraint?).
What I want to achieve is that user can only read and work on tasks they are assignee of.
I found the TASK_WORK Permission but it applies for all Tasks.
Do I really have to set a Authorization for each known task in the system (set taskActivityId as Resource_Id) or is there an other way to achieve my goal?
Best regards,
Markus
