[xwiki-users] Problem Deleting Space - xwiki-users@xwiki.org

6 Mar 2009

I'm using the xwiki snippet code to delete spaces.  I've had success  
with a few of them, but I've run into a problem.

When trying to delete on particular space, I get the following error:

Error number 4001 in 4: Error while parsing velocity page  
Rocks.deletespaces Wrapped Exception: Failed to evaluate content with  
id deletespaces

Error number 4001 in 4: Error while parsing velocity page
