Issue

  • When I use the OOTB Account object by adding a relation to a custom object that includes aggregation fields and a custom picklist field, the aggregation fields are returning as an empty string ““ from the API response.

Steps to Reproduce:

  1. Start 2025.q1.2-lts

  2. Create a Picklist with at least one entry (e.g., "Foo") from Control Panel → Object → Picklists.

  3. Add a custom field named "picklistField" of type "Picklist" to the Account object definition, selecting the Picklist created in step 1.

  4. Create an Object (ObjectA) and publish it.

  5. Create a one-to-many relation from Account to ObjectA.

  6. Add a custom field "countB" of type "Aggregation" for the relation, using the aggregation function "Count".

  7. Create an Account from Control Panel → Accounts → Accounts and note its accountEntryId.

  8. Insert a new record into accountentry_x_20095 using the noted accountEntryId and set the value "Foo" for the picklist field (picklistField_).

  9. Clear the database cache via the Control Panel → SYSTEM → Server Administration → Cache Actions.

  10. Use the Liferay API Explorer “GET” (e.g., /o/headless-admin-user/v1.0/accounts/{accountId}). The response correctly includes the picklist field with the value "Foo" and the aggregation field countB with the value "0".

  11. Delete the corresponding record from accountentry_x_20095.

  12. Clear the database cache again via the Control Panel.

  13. Re-run the API call. Now.

Actual Result: The fields are returning an empty string value ““.

Expected Result: The fields should the correct values because the aggregation reference remains.

Environment

  • Liferay Quarterly Release 2025.q1.2-lts

Resolution

    • The Aggregation Fields were never supported for System Objects "OOTB" (such as Account). This is why it is always returning 0 or empty string. A feature request is under review by the Product Team to address this case: LPD-51575
    • To check on the progress of the request, you can ask at the Liferay Ask link: https://liferay.dev/ask/questions/feature-requests
