[Building Sakai] Class lists Exception

[Daniel Merino]

Hi all.

In all our courses (not in projects) we have the "Edit class list" 
option in the Site Info tool. When we click the option, we get the next 
option "Add class list". Clicking on it gives us one exception, which I 
paste at the end of this mail.

We think that this exception could be related to several concurrence 
problems we are experiencing in the Site Info tool.

Is there a way to deactivate the class lists management in courses? We 
took off the group management in projects (cause we are using sections) 
with the site.upd.grp.membership, but I don't see permissions related to 
the class lists.

Our exception:

/WARN: Exception calling method doMenu_siteInfo_addClass
