I just realized that there are two ways to duplicate object.
- Right click the linked object inside a page, and choose “duplicate”
- Click the three-dot button and choose “duplicate object”
These two methods are different. The first one is a shallow copy and it returns an object with the same ID, while the second one is a deep copy, which return a modal containing all the contents, but IDs are different.
The first one keeps the same link structure with other objects, but the second one is born an orphan.
Perhaps you guys have noticed that , but I didn’t found this in doc or somewhere. So I write it here if someone needs this.
