Can't adjust Page Layout in Panel Wizard

[justin_robbins at cotyinc.com]

Hello everyone,

I tried to use the Panel Wizard to change the Page Layout from the default setting of "Right Column" to "Left Column".  When I clicked "Save the new layout" I received a prompt "The layout has been saved properly".  However, a stack trace was written to the console.  I am now left with no side columns at all.

What am I doing wrong?

Here's the message that is now written to the console when I navigate to the Panel Wizard page.

I have installed xwiki-enterprise-1.1-milestone-3 on a Windows XP machine.  For now, I'm using the default HSQL database and Jetty web server.
