Don:
If the answer to the original problem turns out to be no, I can put this one in the SDM also if you request.
The logic problem is that the column in question is set to 't' when the new subfolder is created, and never changed. I think it should become 'f' when/if an application is mounted at that node in the tree. And it should be reset at unmount-time.
Additionally, there is a misplaced brace in the site map code such that when the column (for that node) is set to 'f', all links are not displayed, including things you want like unmount.
I figured out the second fix, but I am still working on the first one (i.e. application-mount time).
Regards..
