[Solved] How to update records in entity based on view with distinct

Question

Hi
- I have a relational view of the form:
SELECT DISTINCT
FROM TAB1, TAB2, ...- I created instead of triggers for delete, update and insert.
- I created an entity object on this and an updatable view object
- I added this to my module.
- Then I test the view object in the module (module > test), and if I try to update an existing record, I receive the error:
(java.sql.SQLException) ORA-02014: cannot select FOR UPDATE from view with DISTINCT, GROUP BY, etc.
So, ADF internally create as select FOR UPDATE cursor to update the modified record and as the error shows, this is not possible on a view with distinct, ...
Is there a way to work around this error without to rewrite the view?
I was thinking that there is maybe a way to force ADF not to use the select FOR UPDATE and use UPDATE .. SET <value> WHERE <pk>, or maybe to create a new instead of trigger to catch the select FOR UPDATE?

Arti,
Here's another solution (that will still use locking, and can help avoid the "lost update" problem):
