Martin Grigorov commented on WICKET-6392:
-----------------------------------------
There is no class `SimpleMessageValidation` in Wicket. Please provide a
quickstart without 3rd party classes that shows the problem and I'll reopen
this ticket.
Any Component may have any kind of feedback message (info, error, warning,
...), so this API shouldn't be related to Form class. But as I said: the best
place to discuss such things is dev@ mailing list.
> Can not change Model when form has Validation Errors
> ----------------------------------------------------

> Key: WICKET-6392
> URL: https://issues.apache.org/jira/browse/WICKET-6392
> Project: Wicket
> Issue Type: Bug
> Affects Versions: 8.0.0-M6
> Reporter: Kamil
>
> 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"
