Change the converter on a binding in Vaadin 10 Flow?

Question

When establishing a binding with binding-builder, we can specify a converter to mediate between types such as using a String oriented TextField to work with a backing value of type Integer.

binder
.forField( this.phaseField )
.withConverter( 
    new StringToIntegerConverter( "Must enter an integer number" ) 
)
.bind( Panel::getPhase , Panel::setPhase ) ;

Is there some way to get/change/replace that converter later, after the binding is established?

You just need to remove the Binding and then add it again with the new Converter. You can't just hot swap the Converter — Jay, Jul 12 '18 at 08:11
You could also implement a wrapper/proxy converter that delegates to a another converter which can be exchanged then. — Steffen Harbich, Jul 12 '18 at 10:42

No

No, you cannot replace the Converter by itself.

Workarounds

A couple of possible workarounds:

Remove the binding, replacing it with a fresh Binder.Binding using your different Converter.
Implement the original Converter as a wrapper/proxy that delegates to another converter. Switch out that delegate as need be.
