[Zope] How to disply a property of an object created with a Z class

[Satheesh Babu]

you will need to actually get the object from the string id

<dtml-with "_.getattr(this(), document_id)">
<dtml-var body>
</dtml-with>

Or simply

<dtml-var "(_.getattr(this(), document_id)).body">

I've not tested this. See the cookbook entry at:
