public class DelegateValueChangeListener extends Object implements ValueChangeListener, StateHolder
This class is used in conjunction with ValueChangeListenerTag. When a tag like this is in a jsp page: <f:valueChangeListener binding="#{mybean}"/> or <f:valueChangeListener type="#{'anyid'}" binding="#{mybean}"/> The value of mybean could be already on the context, so this converter avoid creating a new variable and use the previous one.- Version:
