Using QSqlRelationalTableModel issue

[Einior]

Hi all,

I use Qt to get an access to PostgreSql DB, but I get a QtSqlError in runtime and can't find more information about it in net.
I have two tables at DB:

@CREATE TABLE "session"
(
"sessionID" integer NOT NULL,
"userID" integer NOT NULL,
"packetsSent" integer,
"packetsReceive" integer,
"loginAutorization" boolean NOT NULL,
"biometricAutorization" boolean NOT NULL,
"autorizationAttempts" integer NOT NULL,
CONSTRAINT session_pkey PRIMARY KEY ("sessionID")
)
WITH (
OIDS=FALSE
);@

@CREATE TABLE token
(
"tokenID" integer NOT NULL,
"sessionID" integer NOT NULL,
"generationTime" time without time zone NOT NULL,
"expiredTime" time without time zone NOT NULL,
CONSTRAINT token_pkey PRIMARY KEY ("tokenID"),
CONSTRAINT "token_sessionID_fkey" FOREIGN KEY ("sessionID")
REFERENCES "session" ("sessionID") MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION
)
WITH (
OIDS=FALSE
);@

I use QSqlRelationalTableModel to get data from DB and QTableView to display it. Relations between tables are coded by QSqlRelationalTableModel::setRelation():

@model->setRelation(1, QSqlRelation("session", "sessionID", "sessionID"));@

EditStrategy for model is set to OnManualSubmit.
Then I change some data in table and try to save it by using QSqlRelationalTableModel::submitAll() I get an error:

bq. ERROR: column reltblal_1.sessionid does not exist LINE 1: SELECT token."tokenID", relTblAl_1.sessionID, token."generat... ^ QPSQL: Unable to create query

I have some other tables and get this message for ever table which contain foreign key. The same message is seen even if I don't change anything and try to submit all.
It's probably can be correlated with "QTBUG-15989":https://bugreports.qt.nokia.com/browse/QTBUG-15989 , but I don't sure.
I'll be happy to receive any comments about this.
