Directory created in CMSAdmin not visible

[sitongia]

2.2.1RC2
Mac OS X
port 8080 with Apache using JK to proxy

When I use CMSAdmin to create a folder, when I click on the Create button, the CMSAdmin portlet disappears. I have to use the Back button to get back to it. The folder is not created.

I see that Destination is filled in from the navigator to the right, and cannot be edited. The name is the name of the directory created. I've tried creating under / and under /default. So, I think I'm using it right.

Strange as it seems, this may be caused by using JK. When I connect directly to my server on port 8080, the create operations work!
