TransformerException: Empty expression! problem on new installation

Yo!

I now have a small test installation to play with. Two problems:

trivial: IPv6 apparently doesn't work. localhost resolves to ::1 on my 
machine apparently, and this gives me [0] (whenever I try to access a lenya 
URL.) I can always use 127.0.0.1, though, so no problem (or I could, of 
course, change /etc/hosts.)


Not so trivial, for me:
enter a publication (default or blog) and try to log in as editor. Same 
problem as described in 
<http://archives.real-time.com/pipermail/cocoon-users/2004-June/052401.html>, 
so I guess there is a solution somewhere. [1]

lenya 1.2 incubating release
cocoon 2.1.5.1
tomcat 4.1.30 (-6 debian package)

More details about my setup is, of course, available.

comments?
thanks

A good idea will be to publish the new docos. The change of to SVN repo is
a big step from my POV. That way, people will not be confused about that.

WDYT?

Yes. The conversion happend very recently. I announced it on
lenya-users and lenya-dev, but nobody had the time to update
the website by now.

The documentation has been updated in the repository, but not
yet published on the Lenya website. Sorry for the inconvenience.

But nothing about svn.

Is the subversion repo pushed to cvs for anonymous access? Or is 
documentaton just lagging?

Ok, some google skills were handy, but documentation would be nice :-) 
(Yeah, I know, better and funnier things to do than writings docs... ) 

Ok, now running
 $ svn co http://svn.apache.org/repos/asf/incubator/lenya/branches/BRANCH_1_2_X lenya-svn

Take a look at the email archives for the mailing list.  this issue
was discussed.  I believe a later release has the fix for this.

Check to see that you have the proper version, and only those
versions, of xalan and xerces.  The wiki discusses which are the
right versions.
