JPQL Designer - Tuple

I was trying to use the Tuple option to get the result of fields mix of Entities and sum of values and seems the Studio has a very good option but not sure how to get the Entity and values from the resultList and didn’t find any documentation on it.

This generates:

final List<DpsAcctStatement> dpsAcctStatementList = dataManager.load(DpsAcctStatement.class)
                .query("select d.dpsAccount, SUM(d.amount) from dps_DpsAcctStatement d where d.dpsAccount.dpsStatus = :dpsAccountDpsStatus1 group by d.dpsAccount")
                .parameter("dpsAccountDpsStatus1", DpsStatus.APPROVED)
                .list();

However, when I run, I get the following exception:


DevelopmentException: DataManager cannot execute query for single attributes

Any code snippets would help
