Vaadin8/Binder question

Hi,

  I've been playing around with the Binder for updating fields in a POJO but how would you bind to a simple String like

String s = ...
ComboBox<String> ss = ...
Binder<String> b = new Binder<>(String.class);
b.forField(ss).bind(String::whatgoeshere, String::whatgoeshere);
b.setBean(s);

Sorry if it's a general functional interface question...

I know it is not a good netiquette to answer a question with a question but why do you want to bind to a String? I don't know if it is even possible as String is immutable (and is definitely no Java Bean). And why bind to it? You can get the String with comboBox.getValue().

Yep, I know about the string immutability and I know I could read the value from the component or use VCL:s to update the String etc, I was just curious in general if you could use the same semantics for all binding...
