Bind variables not available when overriding criteria item clause

Question

Hello -
Using jdev 11.1.1.3.0. Using ADFBC.
In a view object I am overriding getCriteriaItemClause in order to produce a clause for a view criteria of the form
my_column in ( select a_column from a_table where a_field = :MyBindVariable )I have created the bind variable ("MyBindVariable") for my view object and checked the "Include bind variable accessors" box in the Java options panel for the view object. When I use the view object I call the setMyBindVariable method with a value before I call the execute method. However, when
I call the execute method it gives a JBO-27122 error.
oracle.jbo.SQLStmtException) JBO-27122: SQL error during statement preparation.  Statement: << query here, with the appropriate where clause that refers to the bind variable >>
----- Level 1: Detail 0 -----
(java.sql.SQLException) Missing IN or OUT parameter at index:: 1I have tested this code by running the application module tester. With it I am:
1. Right-clicking on my view object and selecting "Operations"
2. Choosing the setMyBindVariable operation, providing a parameter value, and hitting the "Execute" button.
3. Choosing the getMyBindVariable operation, hitting the "Execute" button and verifying that I get the right value back.
4. Right-clicking on my view object and selecting "Re-execute query". I get the JBO-27122 error as described above.
2nd approach (this also didn't work): I have additionally tried creating the clause above using the bind variable value instead of the reference. In getCriteriaItemClause, I would call getMyBindVariable to get the bind variable value and construct the above clause this way:
my_column in ( select a_column from a_table where a_field = literal_value_stored_in_view_object_bind_variable )However, when I tried this approach, getMyBindVariable always returned null.
Is there some reason why the bind variable isn't "available" when executing the query even though I specifically set it?
Thank you for reading my question.
