[Duplicate]Deleting duplicate properties or parameters

[ASF]

If I create a view parameter or custom property with the same name as an existing parameter/property, it is (correctly) flagged as a duplicate by the designer. Then when I select one of the duplicates and delete it, it deletes both instances, not just the duplicate. Is this a bug?

[Bug-12661] Duplicate Property Key Corrupts Original Property Value

I’ve opened an internal ticket for this one. The fix to defer updates is actually doing what it is supposed to - this is just a side-effect; originally, a key was written to the View after each key press (which is why you had an instant collision), which no longer happens. The fix for the key deferment did not include any acceptance around preventing name collisions.
