Why not just put a filter on your 'global' feedbackpanel and filter out
the messages that you already display for each component? E.g. I have
the following code in a form:
private void addGlobalSubmitPanel() {
final List<FormComponent> components = getFormComponents();
final FeedbackPanel feedback = new FeedbackPanel(FEEDBACK);
feedback.setFilter(new IFeedbackMessageFilter() {
public boolean accept(FeedbackMessage message) {
return !components.contains(message.getReporter());
}
});
add(feedback);
}
private List<FormComponent> getFormComponents() {
final List<FormComponent> components = new
ArrayList<FormComponent>();
visitFormComponents(new FormComponent.IVisitor() {
public Object formComponent(IFormVisitorParticipant
formComponent) {
final FormComponent fc = (FormComponent)formComponent;
components.add(fc);
return Component.IVisitor.CONTINUE_TRAVERSAL;
}
});
return components;
}
