I had encountered this issue and for one of my training classes, I threw
together a solution. Your post prodded me to go ahead and post my
solution
as a blog post. After dusting off my long-forgotten blog, here it is:

-messages-that-arent-rendered-by-other-feedback-panels/ (or
http://bit.ly/eHUEuN if that gets chopped up).
Your solution is quite nice but I have a request: you use
ComponentFeedbackMessageFilter. What if I wanted your functionality in
some component only - not whole page - using ContainerFeedbackMessageFilter.
Example:
instead of yours:
// create the form above
form.add(new FeedbackPanel("feedback", new
ComponentFeedbackMessageFilter(form)));
final TextField name = new TextField("name", new PropertyModel(productModel,
"name"));
name.setRequired(true);
form.add(new FeedbackPanel("nameFeedback", new
ComponentFeedbackMessageFilter(name)));
form.add(name);
final TextField price = new TextField("price", new PropertyModel(productModel,
"price"));
price.setRequired(true);
price.add(new MinimumValidator(0d));
form.add(new FeedbackPanel("priceFeedback", new
ComponentFeedbackMessageFilter(price)));
form.add(price);
I would love:
// create the form above
form.add(new FeedbackPanel("feedback", new
RenderOnlyWhatMyChildrenMissedFeedbackMessageFilter(form)));
^^^^^^^^^^^^^^^^ [1]
final TextField name = new TextField("name", new PropertyModel(productModel,
"name"));
name.setRequired(true);
form.add(new FeedbackPanel("nameFeedback", new
ComponentFeedbackMessageFilter(name)));
form.add(name);
final TextField price = new TextField("price", new PropertyModel(productModel,
"price"));
price.setRequired(true);
price.add(new MinimumValidator(0d));
form.add(new FeedbackPanel("priceFeedback", new
ComponentFeedbackMessageFilter(price)));
^^^^^^^^^^^^^^^^^^^^^^^^^6 remove this line.
form.add(price);
This way nameFeedback renders messages for name component
"feedback" renders messages for "price" and other components left
without own feedback panel but NOT from "name" as those messages would
be rendered twice.
All we need is a slight modification of AllExceptFeedbackFilter that
would take a root component instead of assuming page instance.
You code from example then could look something like;
// create the form above
final TextField name = new TextField("name", new PropertyModel(productModel,
"name"));
name.setRequired(true);
form.add(new FeedbackPanel("nameFeedback", new
ComponentFeedbackMessageFilter(name)));
form.add(name);
final TextField price = new TextField("price", new PropertyModel(productModel,
"price"));
price.setRequired(true);
price.add(new MinimumValidator(0d));
form.add(price);
form.add(new FeedbackPanel("feedback", new AllExceptFeedbackFilter(form)));
hope you like the idea.
