QSqlRelationalModel::setFilter with QSqlRelationalModel::setRelation

QSqlRelationalModel::setFilter doesn't work in conjunction with QSqlRelationalModel::setRelation as it is in this code:

Code:

---

model->setTable("table");
 
 model->setEditStrategy(QSqlTableModel::OnFieldChange);
 
model->setFilter("id > 0");
 
model->setRelation(2, QSqlRelation("legaltype", "ID", "legaltype"));
 
model->select();

---

table is not populated with data :((
