SQLite :: Unable to read sql view which has aggregate functions

[Alin Glow]

Hello.
I have strange error when trying read view (SQlLite) whith aggregate functions to QSqlRelationalTableModel.
QSqlRelationalTableModel->select() failed with message:
"no such column: group_concat(trolleybus.id) Unable to execute statement"
Similar error occurred when i try replace/link foreign key to show column "group_concat(trolleybus.id)" in QSqlRelation.
SQLite:
@CREATE VIEW [view_maintenance_trolleybus] AS
SELECT maintenance.id, maintenance.name, group_concat(trolleybus.id)
FROM maintenance
LEFT OUTER JOIN
trolleybus
ON
maintenance.id = trolleybus.maintenance_id
GROUP BY maintenance.id;@

Same SELECT works as intended in QSqlQueryModel.
