Issue
- I want to know if the IDs that can be seen on the UI for Web Content articles, Structures, Templates can change after exporting and importing them on the same or a different site.
- We did a test where we exported a web content article and imported it to another site, the ID changed every time. We also observed that the DDM Template key that relates the template to the structure was the only one that did not change.
Resolution
- Most of these IDs are expected to change so this is the intended behavior of Liferay.
- This is because UUID is designed to be treated as unique.
- You can find that value in the
journalarticle table, in a field called uuid_.
This field contains a long string that provides a unique identifier for the given element.
List of Web Content-related Element IDs:
-
Web Content article ID: will change.
-
Structure ID: will change.
-
DDM Template Key: will not change. This ID connects the structure and the template so it is important that the ID remain the same.
-
Template ID: will change.
