Sounds more like data binding than data provider? Regardless Click doesn't support the concept of implicit binding. It does however support explicit binding through copyTo/copyFrom or field.setValue/field.getValue. If you are interested in GUI patterns here are some interesting reads: Presentation Model - http://martinfowler.com/eaaDev/PresentationModel.html (which relies heavily on implicit Binding) Passive Screen - http://martinfowler.com/eaaDev/PassiveScreen.html (uses explicit binding) Kind regards Bob
