LocalFS has a property "Display in Tree View" which says:

This controls whether the Local File System object will be displayed in the management tree and other instances of the <dtml-tree> tag.

Indeed, checking this box causes the tree to appear in the left zope panel, but if I create my dtml method then the localFS can not be traversed in a dtml-tree. The localFS displays as a branch but there is no '+' to traverse it.

Any thoughts?

Perhaps if you give us the source to your dtml method. --jfarr
