> I have created a query in components xml and added a restriction using the <framework:restrictions> tag.  The restriction should add a where clause, but instead it is adding an "and", thinking the "where" is already in place.  I assume this is because there is a "where" statement in a subquery contained in the ejbql.
> Here is the entry in components.xml which causes the error.

>     </framework:entity-query>
> I can work around it by removing the restriction and adding a where clause to the ejbql, but have reasons for wanting to use the <framework:restrictions> tag instead.
> Here is some of the stack trace I used to determine that an "and" was being placed into the query by Seam when a "where" should have been created:
