How to set up and validate locally
The easiest way to get an alert currently is to create a work item that has child tasks, then try to toggle confidentiality on the parent.
- Check out this branch
- Create or locate in your GDK a work item that has one or more child tasks, all of which are not confidential
- Open the parent work item in a full page view.
- Attempt to toggle confidentiality. An error alert will appear. It will be correctly positioned at the top of the work item detail.
- Scroll the work item. The work item sticky header will appear and the alert will move to be beneath the sticky header.
- Open the same parent work item in a drawer, for example from the project issues list page, and repeat steps 4 and 5. You will see that in a drawer, the alert is now positioned correctly both when scrolled to the top of the drawer and when scrolling down and revealing the work item sticky header.
