Adding OR condition gives ORA-00920 error

Question

I am trying to write a xquery like this -
for $VAR3 in document("DS")/db/V_ViewName where (($VAR3/CODE eq $#PARAM of type xs:string) or (xf:empty($#PARAM of type xs:string)))
     return
     <stuff>
          <stuff_name>{  treat as xs:string(xf:data($VAR3/STUFF_NAME)) }</stuff_name>
     </stuff>
But when I run the query in data view builder I get the following error -
RemoteException occurred in server thread; nested exception is:
     java.rmi.RemoteException: EJB Exception:; nested exception is:
     java.rmi.RemoteException: Query Execution Error (Run Time) 1-2-3-9: Problem while accessing relational database. (com.enosysmarkets.xmediator.wrappers.rdbwrapper.cursormgr.CursorManagerException:
(1-1)JDBC error occured:
java.sql.SQLException: ORA-00920: invalid relational operator
Why isn't this kind of query allowed?
When an empty query param is passed I want it to return all the rows from the view.
It should ignore the "where" if param is empty.
Any clues?

This is CR185494 on LD8.1 - Bad sql generated when a condition is folded into a boolean and pushed to a database.
I will email the patch.
