[jira] [Commented] (WICKET-6392) Can not change Model when form has Validation Errors

["Martin Grigorov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-6392?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16036694#comment-16036694 ] 

Martin Grigorov commented on WICKET-6392:
-----------------------------------------

You should call `form.clearInput()` in addition to remove the old values.
The validation errors are in the FeedbackMessages associated with each invalid FormComponent. You can use `FeedbackCollector(form).collect().stream().forEach(fm -> fm.setRendered(true))` to remove the errors.

> I have a Modal with Form and Submit button (it is used for creating new users).
> Form has several text fields bound to CompoundPropertyModel.
> Everytime I open the Modal, I set  the ModelObject as new User();
> It works fine (fields "see" new model if I cancel the window or if I sumbit it without erors).
> If Form has validation errors, even if i set compoundModel.setObject(new User()); fields have old value and validation erros are present.
> I found [workaround|https://stackoverflow.com/questions/8879775/apache-wicket-how-to-update-model-after-validation-error] but I believe it should be possible with Wicket without "workarounds"
