Feedback/Error message.
Hi.
Loving Wicket so far! I had a search and had trouble finding the answer to
this one, if anyone can help:
1) I have a simple form with username/password and a submit button.
2) User enters username/password and hits submit.
3) onSubmit authenticates against the database through a load on a
LoadableDetachableModel, and returns the result as the model's object.
Let's say there is an error on authenticating against the database - what is
the easiest way of giving the user feedback that his username/password was
wrong? I naively thought I might be able to do some sort of conditional
insert of a component into the page or form (similar to Tapestry).
My solution was then to add a panel (regular not feedback) to the page which
consists of an error icon and a custom message. I would like to update this
component on the re-render so it doesn't display if there isn't a problem,
but it does if there is a problem (couldn't get isVisible working this way).
What's the Wicket way?
Many thanks, Graeme.

add(new feedbackpanel("feedback"));
onsubmit() {
user u=authenticator.auth(username, password);
if (u==null) {
error("Invalid password");
} else {
if (!continuetooriginaldestination) {
setresponsepage(application.get().gethomepage()); }
}

Hey!
Cool - add a feedback panel then set error - I like that! I didn't get to
that part in the Wicket in Action as yet but I see how it works!
Actually - my authentication method is very similar to the one on the book
(again not got to that part yet), so I'm pretty psyched I'm heading in the
right direction!
I'm assuming if I wanted a panel with an icon and an error message I just
create a component with a feedback panel and an image and populate
accordingly?
Cheers, Graeme.
