Check if duplicate statement is about to be created
Closed, DuplicatePublic


When editors click on "add a statement", they may create a statement that is already existing on the Item page (same property, or same combination property-value).

In order to avoid creating duplicated statements by mistake, we need to 1) inform the editor before saving if they are about to create a duplicate 2) provide them a smooth path to either keep editing, save anyway, or redirect to the existing statement.
