How to detect if a view is 'dirty'?
I'm just developing a Web Dynpro application with which the user can edit product information. The view has a lot of input fields and drop-downs. The view also has a Save button that should only be active if the user has modified at least one piece of data. Is there a generic way to detect user modifications or do I have to add an action to each widget? Is there something like an isModified method or a kind of property change mechanism?
