I'm trying to make a navigationpage consisting of two trees with a <hr> between them. Here's the offending code snippet: <dtml-tree branches_expr="objectValues(['Folder'])" single=1 sort=title> <IMG SRC="<dtml-var icon>"> <a href="<dtml-var tree-item-url>" target="MainWindow"><dtml-var title></a> </dtml-tree> <hr width="90%" align="left"> <dtml-tree endusermisc branches_expr="objectValues(['Folder'])" single=1 sort=title> <IMG SRC="<dtml-var icon>"> <a href="endusermisc/<dtml-var tree-item-url>" target="MainWindow"><dtml-var title></a> </dtml-tree> The problem: Having both trees "enabled" (with or without dtml-comment), expanding a node gives the error: Error Type: AttributeError Error Value: 'tuple' object has no attribute 'append' Traceback: Traceback (innermost last): File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/Zope/__init__.py, line 201, in zpublisher_exception_hook (Object: ElementWithAttributes) File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: NaviBar) File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: NaviBar) File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/OFS/DTMLMethod.py, line 145, in __call__ (Object: NaviBar) File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: NaviBar) File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/TreeDisplay/TreeTag.py, line 154, in render (Object: endusermisc) File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/TreeDisplay/TreeTag.py, line 227, in tpRender (Object: ElementWithAttributes) File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/TreeDisplay/TreeTag.py, line 543, in apply_diff (Info: ([None, (['AAAAAAAAAXQ=', []],)], ['AAAAAAAAAh4='])) AttributeError: (see above) Can't I have two trees in one document?
