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

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.

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

Form components in ListView cleared if ListView is refreshed

[Arunachalam Sibisakkaravarthi]

Hi guys,
I have a form that has a text field with Email validator in a ListView (I
want get list of email addresses from user)
When invalid email is entered and listview is refreshed then Text field is
cleared
whereas Text field is not cleared when valid email is entered and listview
is refreshed
I don't want to clear even invalid email addresses when listview is
refreshed.
I want the form components in the list view to be validated  only when the
form is submitted.
Is it possible to address this concern in list view?
