dear all,

I am having trouble restricting the access of a document to my XWiki registerd users only.

If i apply the edit, view rights to XWiki.XWikiAllGroup at the last document published, I get the following error message when logout :

Error number 4001 in 4: Error while parsing velocity page Main.WebHome Wrapped Exception: Invocation of method 'formatDate' in class com.xpn.xwiki.api.XWiki threw exception class java.lang.NullPointerException : null

While when I do the same for an older document, this document is effectively hidden when I logout but the others appear in double!

Any idea?

Many thanks in advance,

Arnaud Béchet
