wicket enclosure not finding child!?

I just upgraded to 1.4.3 from 1.4.0 and now I'm getting this:

org.apache.wicket.WicketRuntimeException:Could not find child with id: mediaOutlet.name<http://mediaOutlet.name> in the wicket:enclosure org.apache.wicket.markup.html.internal.Enclosure.checkChildComponent(Enclosure.java:220)
org.apache.wicket.markup.html.internal.Enclosure.ensureAllChildrenPresent(Enclosure.java:262)
org.apache.wicket.markup.html.internal.Enclosure.onComponentTagBody(Enclosure.java:169)
org.apache.wicket.Component.renderComponent(Component.java:2617)
org.apache.wicket.MarkupContainer.onRender(MarkupContainer.java:1512)
org.apache.wicket.Component.render(Component.java:2448)
org.apache.wicket.MarkupContainer.autoAdd(MarkupContainer.java:229)


<wicket:enclosure child="mediaOutlet.name<http://mediaOutlet.name>">
   <div class="details-subhead font-xsmall font-dgray strong">Media Outlet (<span wicket:id="mediaOutlet.name<http://mediaOutlet.name>"/>):<BR>

Global FeedbackPanel and ComponentFeedbackPanel on the same Page ?

Posted by bh...@actrix.gen.nz.

Hi,

It appears that Wicket already has everything I need:

- A global FeedbackPanel for any messages not necessarily associated
with components (a call error(...) displays the message on it)

- An individual ComponentFeedbackPanel for messages belonging to and
displayed in context of components.


My question is: Should I use both on the same page, and if so, how?

When I use both, then an error filtered by a ComponentFeedbackPanel is
also filtered by FeedbackPanel and the error is displayed twice, in
both panels.

I tried to avoid this by:

IFeedbackMessageFilter filter = new IFeedbackMessageFilter(){

    public boolean accept(FeedbackMessage message) {
        return ! message.isRendered();
    }

};

FeedbackPanel feedbackPanel = new FeedbackPanel("feedback", filter);

ComponentFeedbackPanel componenFeedbackPanel = new
ComponentFeedbackPanel("fedbackText", textField);

But this simple approach fails because FeedbackPanel gets the message
before ComponentFeedbackPanel :(

I would rather not add a not-to-do list to FeedbackPanel, as I would
really like to keep this simple. Especially because
message.isRendered() looks useful.

Any ideas?

Many thanks.

Bernard
