All Broken Links extension does not seems to work

Hi,

I have an issue with the extension "http://extensions.xwiki.org/xwiki/bin/view/Extension/All+Broken+Links". Both scripts does not seem to work in XWiki 7.4.1.

Steps to reproduce:

• Create a page "BrokenLinks" containing the script (see attachment in the extension)
• Create a empty page Link1
• Create a page TestBrokenLink, containing a link to Link1
• Delete Link1
• Open "BrokenLinks"

Actual result:
The link Link1 does not appear

Expected result:
The link Link1 should appear as a broken link.

Besides, when I click in Link1, the first time it says the link is not found, but after a refresh, XWiki opens a popup to create the missing page.

Thank you.
