> The error I am receiving is that the property Account cannot be found in type ISIS.Data.Core.Account. BankAccount is a subclass of Account. I am trying to apply an expression only against BankAccounts in the database. It looks like it doesn't know this. If there was some way to case payment.Account in HQL, that would fix it. What is the solution?
