[xwiki-users] All New Pages Are Orphaned

I've submitted this question before. I was told that no one could replicate this on xwiki 3.x. At the time I was running 2.7. I have just upgraded to xwiki 3.1. Whenever anyone creates a new page on my wiki, it becomes an orphan. If I try to edit the page and use the little "parent editor" box at the top of the editor, I can correctly add the parent. At that point, the full bread crumb trail shows up properly. But when I save that page, the bread crumb trail disappears and the page is still an orphan. It shows as an orphan in the Document Index and the page's Information shows "No Parent". What's the deal? I started seeing this when I upgraded from 2.4 to 2.7. And I'm still seeing it with 3.1. I think the only thing I changed when I upgraded from 2.4 to 2.7 is that I enabled LDAP authentication. But this problem occurs for Xwiki users and LDAP users alike. Would it help to send out any of my config files (xwiki.cfg, hibernate..etc)? Any help would be greatly appreciated. This is a very annoying problem. We're going to have to switch wiki software if we can't resolve this. Thanks, travis
