i need the when we will use dosave() and save() method. plz give some explanation abt tbo
doSave() is triggered when an object is saved via save() method. In your TBO, extend doSave() method if you want to do pre-processing and/or post-processing of save() method.
Through any client, whenever you create a new object type or modify any of the properties of the object type, save() method should be called to save the object.
It happens in webtop too.
To add your own custom code, the dosave() method can be overrided for that particular type. Your custom code will be called whenever save() operation is performed over that object type whatever the client may be.
Refer DFC development guide for more details on TBO.
