Directory listings from Document Mgmt System missing directories

Hi everyone,

I am trying to list the contents of a directory in a document mgmt
system (Xythos) which appears to be implementing WebDAV correctly as
tests e.g. using DAVExplorer (http://www.davexplorer.org) worked flawlessly.

What I am doing is simply a list() call on the WebDavResource
representing the directory in question. What I get as a result is a list
of file names within that directory, along with the directory name
itself. However, the directories contained within that directory are not
included in the ouput.

I have also tried using listWebdavResources() and getChildResources() --
but without success.

Do I need to set any specific parameter to have the sub-directories of
that directory included in the listing? Am I missing something? I have
also played with the DepthSupport options but to no avail.

An example:
Say you have this directory structure:
Dir1
  |-- file1
  |-- file2
  +-- SubDir1
  +-- SubDir2

Ignoring the full path names, I would expect list() to return
  { "file1", "file2", "SubDir1", "SubDir2" }
but instead I get
  { "Dir1", "file1", "file2" }
not necessarily in the given order.

Any help is appreciated!
