Determine the transaction state that is, whether changes have been made to view objects or not

Use the following methods:

ApplicationModule.getTransaction().isDirty() - This method tells you whether the transaction contains any changes in the view objects. This works for transactions made by entity object-based view objects only.

OAViewObject.isDirty() - This method tells you whether a particular view object contains changes or not. This works for both entity object-based view objects and view objects based on OAPlsqlViewObjectImpl. For view objects based on OAPlsqlViewObjectImpl, you can also use OAPlsqlViewObjectImpl.getState() method
