[Zope] Problem with tree and navigate_filter

[Carlos Henrique Bauer]

Hi,

I have an DTML method with the following code:

<!--#tree
id=Outline
branches_expr="navigate_filter('private', 'no',['Folder','File','DTML Document'],'0')"
nowrap='1'
assume_children='0'
skip_unauthorized='1'
-->
 :
 :
<!--#/tree-->

The tree is inserting a plus icon in front of empty folders and file documents.
If I click on that icon it expands the tree. In the case of the empty folder I
get something like:

- Empty folder
   -   Empty folder
        + Empty folder
           
In the case of a document:

- folder
   + file 1
    - file 2
        + file 1
        + file 2

Any ideas?
