I guess so. It must be something in the skinning machinery. My message =
board
application, NeoBoard, has the same skinning machinery as CMF's to give =
it a
skinned look with or without CMF. And it exhibits the same symptoms with
getPhysicalPath() calls. That's why I had to create a new method that
returns the relative path of an article object. The built-in catalog of =
a
NeoBoard instance saves uids like the following:

/a_1 		# first article
/a_1/a_1	# first reply to a_1
/a_1/a_2 	# seond reply to a_1
/a_2		# second article

But visiting an article like the following still duplicates entries in =
the
board's built-in catalog:

/Board/a_1			-> /a_1
/Board/Board/a_1		-> /Board/a_1
/Board/Board/Board/a_1		-> /Board/Board/a_1
...

I think removing **all** instances of the container's id when =
catalogging
article objects should work. Currently, only the first instance is being
removed. I just didn't think acquisition would wreak this much havoc =
when
misused :-(

That works!=20

Thanks for the tip.
