I'm using OpenERP 7.0 and I want to set a ManyToMany relationship between my objects in XML-RPC.

According to the documentation (Unfortunately for Odoo 8.0 and OpenERP 6.0) , I have to use special commands that permit to edit those relationships.

For example to set a new ManyToMany relationship I have to use this triplet :  

(6, _, ids)

Here is my code to create a new message in OpenERP.

    models.execute("execute_kw", asList(
                    db, uid, password,
                    "mail.message", "create",
                    asList(new HashMap() {{
                        put("author_id", 10);
                        put("partner_ids", asList(asList(6, 0, asList(34,54,56))));
                        put("subject", "This is a subject");
                        put("body", "This is the body");
                    }})
            ));

The message is created in OpenERP but the ManyToMany relationship is not set.

So my question is what I'm doing wrong when I want to set this relationship in Java via XML-RPC.
