[jira] [Commented] (WICKET-5979) Feedback.anyMessage() and 1891.10.01 date bug

["Sven Meier (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-5979?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14727844#comment-14727844 ] 

Sven Meier commented on WICKET-5979:
------------------------------------

Feedback.anyMessage()

Problem is that MyFeedback is calling #anyMessage() from #isVisible(), which is called during form submit already. This forces FeedbackMessagesModel to collect all messages *before* your #onSubmit(). These messages are cached until #detach() is called, so MyFeedback shows the additional message on the next request only.

You should follow good practices:

{code}
WebMarkupContainer border = new WebMarkupContainer("border") {
    @Override
    protected void onConfigure() {
        super.onConfigure();
   			
        setVisible(feedback.anyMessage());
    }
};
{code}
