Expressions for one-to-many

Question

Trying to get a query to return all users that have a particular role. The roles are stored in a Vector populated by the Role object in the User object.
I only get an exception because the SQL end with "...WHERE" so no condition is added to the statement...
Where am i going wrong...?
///////BITS OF CODE/////////
ReadAllQuery query = new ReadAllQuery();
query.setReferenceClass(User.class);
//Role selection...
ExpressionBuilder userExp = new ExpressionBuilder();
userExp.anyOf("roles").get("rceRoleId").equal(role.getRceRoleId());
query.setSelectionCriteria(userExp);
///// SQL THAT I WANT TO ACHIVE /////
SELECT uri.uri_username
FROM tdcr_user_roles urs, tdcr_user_info uri, tdcr_role_code tdc
WHERE ( (uri.uri_userid = urs.urs_uri_userid)
AND (tdc.rce_role_id = urs.urs_rce_role_id)
AND (tdc.rce_role_id = 1)
Thanks!

Jan,
You are passing the ExpressionBuilder into the selection criteria and not the expression you created. The ExpressionBuilder is basically a factory for expressions.
Try:
///////BITS OF CODE/////////
ReadAllQuery query = new ReadAllQuery();
query.setReferenceClass(User.class);
//Role selection...
ExpressionBuilder eb = new ExpressionBuilder();
Expression userExp = eb.anyOf("roles").get("rceRoleId").equal(role.getRceRoleId());
query.setSelectionCriteria(userExp);
