I am trying to work my way up through folders, checking whether each folder has a property named 'site_root_folder'. Logically (in *my* head anyway), what I have written below is what I want to do, but I'm not sure that I'm really writing this the write way. I vaguely remember reading that I can't nest dtml-if tags within dtml-in tags. There is no problem whatsoever to use "dtml-if" inside "dtml-in".

...

<dtml-let level=0> <dtml-in level> <dtml-if "PARENTS[level].hasProperty('site_root_folder')"> <dtml-var "PARENTS[level].absolute_url()"> <dtml-else level="level+1"> </dtml-in> </dtml-let> "dtml-in" works with sequences.

In your example, however, you give it an integer ("level"). It will not be happy with this.

You may try:

<dtml-in PARENTS> <dtml-let PARENT="_.getitem('sequence-item')"> <dtml-if "PARENT.hasProperty....> ....

Excellent. Here is what I have managed to make work. <dtml-in PARENTS> <dtml-let PARENT="_.getitem('sequence-item')"> <dtml-if "PARENT.hasProperty('site_root_folder')"><dtml-var "PARENT.absolute_url()"></dtml-if> </dtml-let> </dtml-in> I really appreciate it. And thanks for the reply on my other (related) post. Don't think I'll mess with ZopeFind for now; I don't always have access to Zope 2.2.x, but more usually 2.1.6. Thanks again. tim
