Visual Task Board Cannot Edit Primary Assignee

[ruzzty06]

When editing primary Assignee in Task card view for an Incident. There is a "UI Policy violation" error, but Incident Assigned To can be edited in form view. What could be the problem here?

I ran into a similar situation with one of my user's boards that was caused by a UI policy that made the assigned_to field read only until they selected a valid assignment group.   Could be a similar issue for you? Are there any dependencies for your assigned_to field that aren't being evaluated in the VTB but are in the incident form view?

Complementing Josh's answer, the task table has this UI Policy: Make assignment group mandatory, which your instance must have as inherit:

Since the vtb_task is an extension of the task, it inherits all the UI policies.

And in the case of the virtual task, you are trying to assign the task before having assigned a group. The layout is a bit confusing and the "UI Policy Violation" message alone doesn't help too much.

In short, the issue is that you need to assign a group first, and then you'll be able to assign a primary assignee. To do this, click on the private task link on the top-left corner:

Assign a group here and then, back on your private task, you'll be able to assign the task to anyone in that assignment group.

Hope this helps.

Its an issue with a UI policy, I Disabled a certain UI policy for the VTB view.

What you did is good to know, the question is - how did you do it? How do I go about disabling a particular UI policy for only the VTB view?
