Hello
in V7 we used
String propertyName = (String) binder.getPropertyId((Field<?>) valueChangeEvent.getProperty()); to detect name of changed property in our custom fields.
Plz what si the way to do this in V8?
The data model is different in Vaadin 8, there are no Items or Properties, but you use Java Beans for the data binding.
Yes, I read that
Still the binder uses property names for binding, eitgher explicit or detected using reflection
The events and/or seem to not provide them
The events and/or public/protected API seem not to provide them,
Indeed
We have very complex UI, tree like nested components with many hundreds of fields
That are bound to a model using paths built from property names
That’s something you’ll need to refactor somehow
There’s unfortunately no simple replacement for the old API
That is really brutal and when I am abnout to majke a decision when to use vaadin again I must remember this
If you don’t have another option, you can always monkey-patch the Vaadin files to expose the protected/private members
but that’s a temporary solution at best
Yes, that is what we are investigating now, I hoped that there would be some recommendation about this
Something that would allow us to map valuechanged event to propety name
And with Vaadin 8, there’s always the Vaadin 7 compatibility kit you can fall back to
We are paying fot hat already
