Consider the following. I have 2 ZClasses (n1 and n2) nested within a container Zclass (c) created within a product (p). My addForms for n1 and n2 (call them a1 and a2) are quite complicated but share a lot of code. The obvious solution? Move this duplicated code to a single DTML method (call it shared) and use acquisition to give a1 and a2 access to this code snippet. Just to make sure we have the same mental picture, here's the hierarchy (where indentation implies what children are visible when "clicking" on the parent): Zope Root Control Panel Products p c n1 n2 a1 a2 shared If c was a folder outside the Product hierarchy, then adding shared in the location shown *would* give a1 and a2 access via acquisition. However, within the Product hierarchy, it doesn't. a1 and a2 only acquire shared if I move it up to the level of "c". Why is this? Am I missing something obvious? Just when I think I am coming to grips with Zope ... Cheers, Darran.
