How to map a property to a read-only database columnHello,
I have an XAF business object and one of the properties is calculated by a trigger in my database. I need to show the property on my business forms, but when I utilize the read only approach of PersistentAlias and Persistent, the update statement for the object includes this field and overwrites my database value.
What is the proper way to show this field in the UI, but not update the database.
Thank you.
We have added support for read-only database columns in XPO. If you would like to test this feature prior to the official 18.2 release, get the preview build in the How to map a property to a read-only database column ticket. Your feedback is welcome.
Hello, Robert.
Please refer to the How to map a property to a calculated database column (implement a read-only persistent property) ticket for a possible solution.
I've tried this, but the GetPropertiesListForUpdateInsert never fires in the custom UnitOfWork.
I'm afraid we cannot determine why this method is not called based on your reply. Would you please send a small sample project demonstrating this issue to us?

I just converted to a delayed property and added (true) to the attribute so I am okay for now. Still not sure why this does not fire.
