[Vaadin 7.3.2]
DataBinding with CustomField<com.abc.validation> isModified() always return FALSE

Hi folks, I trying to implement a form that ask the user to SAVE is the data has been modified. So far it works with components that are use directly…
Ex: ComboBox and TextField

Since we are re-using partial form somewhere else in our application, I’ve created a CustomField that could be re-used. My problem is, Even if the dataBinding work as expected (using a FieldGroup) the CustomField method isModified always return FALSE

PS: I have made a cheap workaround using a ValueChangeListener, but I would prefer not having to do that since I may not understand how to do it the RIGHT way in vaadin

Thanks in advance for your help

Sorry to say, but I think the right way to do it would be to use a more recent Vaadin version than 7.3.2 - it was released over 3 years ago and a lot has happened since, including a total rewrite of the data binding mechanism in Vaadin 8.

Can you show your code that how your CustomField is implemented? for example, a Github link?
