-------------------------------------
Assignee: Igor Vaynberg
> ResourceMapper doesn't work: mapHandler() always returns null
> -------------------------------------------------------------
>
> Key: WICKET-3506
> URL: https://issues.apache.org/jira/browse/WICKET-3506
> Project: Wicket
> Issue Type: Bug
> Components: wicket-core
> Affects Versions: 1.5-RC2
> Reporter: Matt Brictson
> Assignee: Igor Vaynberg
> Attachments: quickstart-WICKET-3506.tgz
>
>
> ResourceMapper#mapHandler uses the following code test whether a particular
> ResourceReferenceRequestHandler should be mapped:
> // see if request handler addresses the resource we serve
> if (resourceReference.getResource().equals(handler.getResource()) == false)
> {
> return null;
> }
> Unfortunately this if statement always evaluates to true and thus null is
> returned.
> The problem is that IResource implementations do not provide an equals()
> method. In practice this means that the default Object#equals()
> implementation is used, which nearly always results in false for the equality
> test.
> I see two possible solutions:
> 1. Implement equals() for all IResource classes.
> 2. Compare the ResourceReference objects instead, which already have a
> meaningful equals() implementation. In other words:
> // see if request handler addresses the resource we serve
> if (resourceReference.equals(handler.getResourceReference()) == false)
> {
> return null;
> }
> I'm attaching a quickstart that illustrates this bug.
