The Cairngorm Persistence library's download link on the wiki is broken, and I believe the library is not in the Maven repository.
The Persistence library's download link on the Cairngorm Libraries wiki page is broken.
Also, I cannot find the Persistence Library in the Maven repository list.
To work around the broken link, I can build from the source here: http://opensource.adobe.com/svn/opensource/cairngorm3/trunk/libraries/Persistence/.
Not a show stopper, just wanted to make sure the persistence library wasn't going away.
Link fixed. It seems that an update on SourceForge deleted the attachments from the Wiki pages.
