Hi, A phaselistener may work here, in after phase of restore view, traverse the component tree, if the component is an editablevalueholder, cast the component to editablevalueholder and add the valuechangelistener by addValueChangeListener or setValueChangeListener.
A valuechangelistener implementation needs a processValueChange method or it can be a method binding, in your case the first option is a better alternative See editableValueHolder for more info.
