in my database a have an invoice table and a payment table. i have a transactions view that shows payments and invoices. i created an entity from that transaction view.
in my application i want to be able to add a payment from the transaction screen (which is a datagrid of transaction entities) and that the list of transactions be updated.
right now I can achieve this by saving the changes and refreshing the entity list.
Is there a way to do this without saving changes to the db ? like temporarily adding the payment to the transaction view ?
