Using a transient attribute to indicate a new view object row
For entity-based view objects, there is a simple technique you can use to determine whether a particular row has a new status. The status of a row is new when the row is first created. The row remains in the new state until it is successfully committed to the database. It then goes to an unmodified state. Knowledge of the status of the row can be used to set up enable/disable conditions on the frontend user interface.
In this recipe, we will see how to utilize a transient view object attribute to indicate the new status of the view object row.
