Background

using 'sudo cpan' under Ubuntu linux, I installed XUL::Node. The installed version is 0.06 When reading the documentation, it refers to XUL::Node::Event, which is not in the distribution, so I installed that.

It seems (I am not quite sure about this) that x-n-Event is installed with XUL::Node version 0.05. I had to reinstall XUL::Node. I then found POE::Component::XUL and installed that. No problem installing.

I copied the sample code in the documentation directly into a file, but the script would not run. I got an error relating to the apps key Test not being a callback or code ref. (I did not keep a copy of the original error) So I tried cleaning both POE and XUL::Node from my system (deleting all directories and files), and re-installing. Now POE::Component::XUL will not install. I get the following error:

Conclusion: XUL::Node::State is associated with version 0.05 but not version 0.06.

Question: was that a packaging mistake or part of a redesign? How do I get POE::Component::XUL to work?
