Igor Vaynberg resolved WICKET-2121.
-----------------------------------
Resolution: Won't Fix
Assignee: Igor Vaynberg
the load method of your model can be called after the feedback panel has
already rendered - thus it will not pick it up. it is simply a bad idea to call
any feedback related messages from your model's get methods because you have no
idea when they are called.
> Feedback message isn't displayed

> Error message created with error() method in load() method of
> LoadableDetachableModel isn't displayed on FeedbackPanel. The same happens
> when using AbstractReadOnlyModel.getObject():
> ProblemPage.java:
> public class ProblemPage extends WebPage
> {
> @SuppressWarnings("serial")
> public ProblemPage()
> {
> add(new FeedbackPanel("feedback"));
>
> error("this error message is displayed");
>
> final IModel<String> helloModel = new
> LoadableDetachableModel<String>()
> {
> @Override
> protected String load()
> {
> error("this error message is NOT displayed");
> return "Hello message";
> }
> };
> add(new Label("hello", helloModel));
> }
>
> }
> ProblemPage.html:
> <html>
> <body>
> <div wicket:id="hello">[hello]</div>
>
> <div wicket:id="feedback">[feedback messages]</div>
> </body>
> </html>
