Re: Display component feedback message once: "safety net" renders them always before

[Pedro Santos <pe...@gmail.com>]

Hi Joseph, I didn't understood your solution

If have an page with 3 form components and 5 feedback panels: 1 for each
form component, 1 for the form, and the last one for the page. And I want
feedback messages address to form components to be presented only by the
correspondent feedback panel.
I would create:
FeedbackPanel fp1 = new
ComponentFeedbackPanel("formComponent1FeedbackPanel", formComponent1);
FeedbackPanel fp2 = new
ComponentFeedbackPanel("formComponent2FeedbackPanel", formComponent2);
FeedbackPanel fp3 = new
ComponentFeedbackPanel("formComponent3FeedbackPanel", formComponent3);
FeedbackPanel fp4 = new ComponentFeedbackPanel("formFeedbackPanel", form);
FeedbackPanel fp5 = new ComponentFeedbackPanel("pageFeedbackPanel", page);

formComponent1.info("some message") register an message that will only be
presented by fp1
form.error("some message") register an message that will only be presented
by the form
