Brian Topping closed WICKET-1892.
---------------------------------
> FeedbackPanel can't be conditionally wrapped with background -- problem with
> isVisible propagation
> --------------------------------------------------------------------------------------------------
>
> Key: WICKET-1892
> URL: https://issues.apache.org/jira/browse/WICKET-1892
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.4-M3
> Reporter: Brian Topping
> Assignee: Igor Vaynberg
> Priority: Minor
>
> Our UI person developed a UI where the feedback list was rendered on a light
> red background. The idea is if there is a problem, a large red box would
> visually highlight the rendered list.
> I set a breakpoint at the anonymous implementation of Component.isVisible()
> in the constructor for FeedbackPanel and it is correctly returning false when
> there are no items in the feedback list. And if the code from WIA is used
> with a CSS class, we might presume:
> <div wicket:id="feedback" class="errorBackground"/>
> But this is not the component that is made invisible, it is the child (the
> component with id "feedbackul"). So I tried to wrap this with an enclosure
> using the feedbackul as a child, but I presume because of the special
> late-rendering nature of a feedback panel, it could not be found
> (chicken-egg).
> It seems like the ideal solution is to have the feedbackul component look to
> it's parent and also make it invisible if it's child is invisible, or some
> variety of that. For now, I am going to try subclassing FeedbackPanel and
> have it guess at the child to check visibility. But that's got it's own set
> of ugly... it's a large constructor that needs to be duplicated since the
> code we care about is in the anonymous component created in the constructor
> (so we can't call super and then patch up the returned remains).
> Please let me know if I can provide any other information! :-)
