My namespace gets lost when I try to use the `branches' attribute of the `dtml-tree' tag. Example: <dtml-tree branches=some_method> ... </dtml-tree> `some_method' is a dtml-method with the following template: <dtml-return "objectValues(['Folder', 'DTML Document', 'File'])"> Rendering the dtml-tree results in: Error Type: NameError Error Value: objectValues In this particular case I could use brances_expr="objectValues(['Folder', 'DTML Document', 'File'])", but I plan on augmenting the branch-list with some other objects before returning from `some_method'. `some_method' works fine if I call it using <dtml-var "some_method(_.None, _)">, but apparently this is not the way the method is called by the dtml-tree tag. I also tried <dtml-tree branches_expr="some_method(_.None, _)"> Unfortunately, it seems that the namespace where branches_expr is evaluated doesn't contain the namespace variable `_'. What am I doing wrong? How can I use a DTML-method to calculate the list of branches? By the way, if the branches attribute names a nonexistent method, the tree ends up empty without triggering any errors. I really would expect a name error here. Is this a bug? <dtml-tree branches=no_such_method>...</dtml-tree> -> empty tree. Yes, and I'm using: Zope version: Zope 2.1.2 (source release, python 1.5.2, linux2) Grateful for any help, -- Anton Gyllenberg <anton@lifix.fi> +358-50-3412792
