[Zope] LocalFS and <dtml-tree>

[Aseem Mohanty]

Some more details:

I tried the following different ways:

<dtml-tree name="REQUEST.tree_folder" branches="fileValues">
  <dtml-var getId>
</dtml-tree>

and I get just a list of folders in the folder REQUEST.tree_folder.

<dtml-tree name="REQUEST.tree_folder">
  <dtml-var getId>
</dtml-tree>

I get nothing just a blank page

<dtml-tree name="REQUEST.tree_folder" branches_expr="fileValues()">
  <dtml-var getId>
</dtml-tree>

I get the folders with little '+' signs infront of them but expansion is 
erratic (sometimes it does sometimes it doesnt, one expand click expands 
another node and so on) and then too it only shows the same dir 
structure under it (not the actual one...but the one at the topmost level)

<dtml-tree name="REQUEST.tree_folder" branches_expr="fileValues()" id=id>
  <dtml-var getId>
</dtml-tree>

this is the nearest i have gotten to a proper tree...
all nodes expand out nicely. Only problem is they dont show the true 
contents, they just show the top level contents in themselves (over and 
over again ... infinitely)

 what should I do to get the proper tree??
