Re: Tests based on WicketTester: NPE in ConcatBundleResource.readAllResources
Hi,
Is there a chance that you create a bundle without any resource(reference) ?

OK, I've now isolated any code dealing with resource bundles for
JS and CSS in my Application and created a TestApplication class
in which this isolated method is overridden as empty, so that
resources are not used at all. Now the test no longer fails.
If I should need this piece to work with tests in the future, I
guess I will have to go through the configuration (file system
paths for the stuff loaded in the resources) to get this
working?
Thank you again!

In YourApplication#init() you something like:
getResourceBundles().addXyzBundle(Class, String, resourceReferences*).
For some reason some of the references cannot load its resource data.

Not quite sure I understand this correctly,
I tried avoiding the use of the ConcatBundleResource altogether
by overriding the method that creates it in my Application for
my test. But this did not make any difference.

Die Freiheit ist uns ein schoenes Weib.
