Question about Converters and Data Binding

Vaadin 6 / 7 / 8 Framework Data Binding

Is it a correct understanding that when you use a custom converter you can’t use field binding because you need to manually set the convertedValue?

I’m struggling to map my bean’s String to a TwinSelect list, any suggestions would be appreciated. Seems like a common use case but I can’t find anything written about it.

Thanks,
Fredrik

Field binding to a bean works normally with a custom converter.

For your case, see
this example

Seems it doesn’t recognize the Converter. Looks like the TwinSelector expects a Converter of type Object but the actual type is Set so it ignores the converter unless I’m missing something.

Hmm… But the example works, doesn’t it? Or are you using it with a ConverterFactory? I suppose there could be a problem in that case.
