Roo Finder is not correctly generated

public static TypedQuery<Controlway> Controlway.findControlwaysByGroups(Set<Controlgroup> groups) {
if (groups == null) throw new IllegalArgumentException("The groups argument is required");
EntityManager em = Controlway.entityManager();
StringBuilder queryBuilder = new StringBuilder("SELECT o FROM Controlway AS o WHERE");
for (int i = 0; i < groups.size(); i++)

{ if (i > 0) queryBuilder.append(" AND"); queryBuilder.append(" :groups_item").append(i).append(" MEMBER OF controlway.groups"); // here the 'controlway' is wrong if i change it to 'o' than it works }

TypedQuery<Controlway> q = em.createQuery(queryBuilder.toString(), Controlway.class);
int groupsIndex = 0;
for (Controlgroup _controlgroup: groups)

{ q.setParameter("groups_item" + groupsIndex++, _controlgroup); }

return q;
}

If I start the Roo shell it will override my changes and this is very annoying
