You might want to debug this functionality, then, maybe there is a bug or
maybe something is not happening which is not apparent on your screen.

Without seeing the code I cannot guess more.

Noted Martin Terra.
The Mechanism of showing the validation messages is automatic.

Probably yes, AjaxSubmitLink aj AjaxButton are interchangeable, remember to
setDefaultFormSubmitBehavior(false) to avoid actually submitting and
processing the form.

What is your mechanism of showing the validation messages, is it automatic?

Re: Form components in ListView cleared if ListView is refreshed

[Arunachalam Sibisakkaravarthi]

Hi Martin Terra, thanks for your suggestion.
Yes, currently AjaxLink is used in my case, I should use AjaxSubmitLink to
address the issue where it clears the input.
I just observed another thing that validation happens for all list items,
but the validation message shows only items that present when the listview
is initialized.
but when I refresh the page (pressing F5 on the browser), then all list
items show the validation messages. Any idea on this behavior?

When refreshing component via ajax or other submit, you must use
button.setDefaultFormProcessing(false) to avoid validation.

If you refresh view without button, for example using a Link, a Link does
not submit the input data to the server and thus values are "lost" because
they are never received by the server.

When working with forms, all actions must use a form submitting behavior
(see AjaxFormSubmitBehavior) in one way or another (ajax or otherwise) to
send the values to server (in order for server to be able to repaint them
in response).

Re: Form components in ListView cleared if ListView is refreshed

[Arunachalam Sibisakkaravarthi]

Hi Martin Terra,
Thanks for your feedback, Yes I already used setReuseItems on listview. I
will look at your suggestion.
Data loss happens only when invalid email address is entered (in my case).
Let say If the form component doesn't have validation, then no data loss
when listview is refreshed.
Will data in the form component be validated when listview is refreshed? If
yes, then is it possible to stop that behaviour? Then it will be validated
only when the form is submitted.

Re: Form components in ListView cleared if ListView is refreshed

[Martin Terra]

You can setReuseItems, but the number of your list items changes you will
need to implement some sort of FormComponentReuseManager
