Deleted session or user action properties

[orr]

When trying to create a deleted session property (under my agentless application settings), I'm getting "Tag with key XXXXX was deleted before" error message when clicking on the "Save Property" button.
Is there a way to restore the property?

Afaik it's not possible. You can recreate the property, but you need to specify another key name and you cannot reuse the old one. 

Alternatively, you can delete the application and recreate it (also using the same entityId). This will enable you to reuse the keys, but you will lose all your data for the web application.
