Hello, I am trying to write a tree access to a hyerarchy of folders containing custom objects, subclassed from the DTML Docuement. The inheritance path should be DTMLDocument -> Article (my custom class) -> every single article in the folders. I would like only Articles and folders to appear in the tree, so this is what I do: <dtml-tree branches_expr="objectValues(['Folder','Article'])"> <dtml-if "meta_type=='Folder'"> <dtml-var title_or_id> <dtml-else> <A HREF="<dtml-var tree-item-url>"><dtml-var title_or_id></A> </dtml-if> </dtml-tree> The tree *looks* all right, and the folders expand and contract ok. But the URLs in the HREF are mangled. For example, I have a folder called abracadabra, that contains another folder named curiosidades, that contains an article whose title is "las origines del ajedrez", and that has in id of "ajedrez". The link comes out like this: <A HREF="abracadabra/curiosidades/<string>">las origines del ajedrez</A> I hope this does not play hell with the guys that use HTML-aware mail clients, but what happens is that instead the URL instead of being bracadabra/curiosidades/ajedrez gets the last component of the path substituted with 'string' between angle brackets. If I modify the dtml-tree tag so that it takes in also DTML Documents, *those* URLs work. So what is happening ? Shouldn't the id propery be inherited from my Article class ? It *almost* works, and it is driving me insane. Thanks in advance, Walter -- Vita brevis, ars longa, occasio celeris, experimentum periculosum, judicium difficile.
