I've got to make this work to use tree for my navigation... Can someone please tell me why this: <dtml-tree content branches_expr="objectValues(['Folder', 'DTML Document'])" sort=order > <dtml-if expr="meta_type == 'Folder'"> <span class="menu"><dtml-var title_or_id></span> <dtml-else> <dtml-if expr="id() == 'cnart'"><dtml-var cnartgif></dtml-if> <A HREF="<dtml-var "content.absolute_url()">/ <dtml-var tree-item-url>? <dtml-if tree-s>tree-s=<dtml-var tree-s></dtml-if> <dtml-if tree-e>&tree-e=<dtml-var tree-e></dtml-if> <dtml-if tree-c>&tree-c=<dtml-var tree-c></dtml-if>"> <dtml-var title_or_id></a> </dtml-if> </dtml-tree> (cnartgif is in the root folder. I've tried putting it in the content folder.) results in this: File /usr/local/src/Zope-2.0.0-src/lib/python/TreeDisplay/TreeTag.py, line 154, in render (Object: content) File /usr/local/src/Zope-2.0.0-src/lib/python/TreeDisplay/TreeTag.py, line 250, in tpRender (Object: ElementWithAttributes) File /usr/local/src/Zope-2.0.0-src/lib/python/TreeDisplay/TreeTag.py, line 491, in tpRenderTABLE (Object: ElementWithAttributes) (Info: (['AAAAAAAAALc=', []], {'childless_decoration': '', 'id': 'tpId', 'branches_expr': <method Eval.eval of Eval instance at 85a7300>, 'sort': 'order', 'url': 'tpURL', 'name': 'content', '': 'content'}, [['AAAAAAAAALc=', []]], [['AAAAAAAAALc=', []]])) File /usr/local/src/Zope-2.0.0-src/lib/python/TreeDisplay/TreeTag.py, line 408, in tpRenderTABLE (Object: cnart) AttributeError: __call__ -- ~mindlace
