Interface ValidationCallbackMixin

All Known Implementing Classes:
FileListComponent, MultiFileComponent, SingleFileComponent
public interface ValidationCallbackMixin
Mixin for classes extending UIComponent that implements processValidators(context) by first validating the component itself, then processing its children.

To use this mixin, you need to override validateSelf(FacesContext) and provide your validation logic for the component. In addition, you also need to override UIComponent.processValidators(FacesContext) to point to the implementation provided by this mixin, e.g.: 

@Override
public void processValidators(FacesContext context) {
  ValidationCallbackMixin.super.processValidators(context);
}

This mixin assumes that any class using this mixin is a subclass of UIComponent.
