How to add a class to an empty KB?

[bunyan]

Hello!

I've set up OntoWiki from the repository and tried to create a
knowledge base. However, I was not able to create a new class as
described in http://ontowiki.net/Projects/OntoWiki/Help/Classes -
there is no context menu (white circle). How do I add classes to my
knowledge base?

Thank you.

Hi,

we are currently working on the navigation box to enable different
kinds of hierarchies.
Sadly the button from the old navigation went missing in the trunk.
I am sorry for the inconvenience.

3 options:
- use the stable 0.9 version
- wait
- maybe there is a workaround already:
i tested the following: toggle hidden entries on, select owl:Class,
click "new Instance".
(for some reason it does show up in the list, but not in the
navigation... can someone help here?)

Hi!

I now have 3 OntoWiki versions installed:
1 - from the Mercurial repo, v0.9.5
2 - from the SVN repo, v0.8.5
3 - from Google Code download section, v0.9 (is this the stable
version?)

The only version that has the Classes context menu is #2
I tried the workaround, the owl:class does not show up in the
navigation box after turning the hidden entries option on.
When I tried to search in navigation for "class" or "owl:class", got
the following:

Catchable fatal error: Argument 1 passed to
Erfurt_Sparql_Query2::addProjectionVar() must be an instance of
