Проблемы с фильтром для формы

[Мышелов Федор]

прошу меня извинить это я тестовую версию с One2Many скинул
это в методе init datasources DeliveryWHTKTable

QBDS_DeliveryWHTKFactLine = this.query().dataSourceTable(tableNum(DeliveryWHTKTable)).addDataSource(tableNum(DeliveryWHTKFactLine));
QBDS_DeliveryWHTKFactLine.addLink(fieldNum(DeliveryWHTKTable, DeliveryWHTKId), fieldNum(DeliveryWHTKFactLine, DeliveryWHTKId));
QBDS_DeliveryWHTKFactLine.joinMode(joinMode::ExistsJoin);
QBDS_DeliveryWHTKFactLine.fetchMode(QueryFetchMode::One2One);

QBDS_DeliveryWHTKPurchTable = QBDS_DeliveryWHTKFactLine.addDataSource(tableNum(DeliveryWHTKPurchTable));
QBDS_DeliveryWHTKPurchTable.addLink(fieldNum(DeliveryWHTKFactLine, MovetJournalId), fieldNum(DeliveryWHTKPurchTable, JournalId));
QBDS_DeliveryWHTKPurchTable.joinMode(joinMode::ExistsJoin);
QBDS_DeliveryWHTKPurchTable.fetchMode(QueryFetchMode::One2One);
QBR_VendAccount = QBDS_DeliveryWHTKPurchTable.addRange(fieldNum(DeliveryWHTKPurchTable, VendAccount));
QBDS_DeliveryWHTKPurchTable.enabled(false);

это его же executeQuery

switch (VendAccountSelect.valueStr()) {
   case '':
        QBDS_DeliveryWHTKPurchTable.enabled(false);
        break;
   default:
        QBDS_DeliveryWHTKPurchTable.enabled(true);
        QBR_VendAccount.value(VendAccountSelect.valueStr());
   }

вызов происходит по modified методу контрола
