We usually want questions (and replies) on the mailing list -- for the archives and to help others. paul dunbar writes:
... number of subordinate documents in tree display ... You have two options:
1 "ZopeFind", described in ZQR (Zope Quick Reference). You would use it like this: <dtml-tree ....> <dtml-var "_.len(ZopeFind(this(), obj_metatypes=[...whatever_you_need...], search_sub=1 #probably, 0 if you only #want the direct children ,))"> .... </dtml-tree> 2 Catalog search. You would use a "PathIndex" (available only for Zope 2.4 and up) search combined with a search for "meta type". The "PathIndex" would restrict the hits to documents below the current path (you would need "URL" and "tree-item-url") to form the subquery term. 1) is easier to implement but probably less efficient than 2.
