[Zope] dtml-tree ques

[AM]

I was doing that but unsuccessfully
This is my filtering function:

root = context.pres_docs_storage

obs = root.objectValues()
ob_list = []
for ob in obs:
    if ob.getId() != 'examples': ob_list.append(ob)

return ob_list

This works too: the root is a LocalFS instance, and this function 
returns a list of -

<File ObjectWrapper instance at  8C8B4B8>


My tree method:

<dtml-let root="pres_docs_storage">
  <dtml-tree name=root branches_expr="filter_tree_items()" nowrap single>
    <dtml-var "pres_docs_get_url( getId(),hasChildNodes(), 
_['tree-item-url'], _['tree-item-expanded'])">
  </dtml-tree>
</dtml-let>

If I do this and click on test: it kind of hangs ie my browser just 
keeps churning but never renders the page.

My original tree method:

<dtml-let root="pres_docs_storage">
  <dtml-tree name=root branches=objectValues nowrap single>
    <dtml-var "pres_docs_get_url( getId(),hasChildNodes(), 
_['tree-item-url'], _['tree-item-expanded'])">
  </dtml-tree>
</dtml-let>

This on the other hand works perfectly.

What could be going wrong between the function call and the rendering??

TIA
AM
