Bizarre behavior of a View Criteria for a View Object

Question

Hey,
I remarked quite a bizarre behavior of the View criteria that I created for my view object, using bind variables.
lets say I have the generated query in the View object:
SELECT Paquet.ID,
Paquet.WEIGHT,
Paquet.VALUE,
Paquet.ORIGIN,
Paquet.DESTINATION
FROM PAQUET Paquet
I want to use the executeWithParams with bind variables for this View object.
I create a bind variable:p_o
I create the View Criteria vith the visual editor that generates an additional view clause:
( ( ( Paquet.ORIGIN LIKE ('%' || :p_o || '%') ) OR ( :p_o IS NULL ) ) )
test query works and explain plan as well.
Now, when I execute the view object on a page with the bind variable properly set, I get the error: java.sql.SQLException: Attempt to set a parameter name that does not occur in the SQL: p_o
Then I copy the where clause generated by view criteria visual edito directly to the query and delete the View Criteria, and it ALL WORKS FINE
If has to work like that, then what is the View Criteria useful for? I still think that there is a problem.
Thanks!

Hi,
ViewCriterias are not accessed with ExecuteWith Params. For this the bind variable needs to be in the where clause. Named ViewCriterias are listed separately in the DC list
