TFs are evil. They are the wrong solution to a real problem. A better solution for clutter is the CMF skins tool. Even if you only use the CMF to get the skins tool and put a non-CMF zope application within a portal folder, this is much better than using TFs. In Zope 2.3, TFs will break sessioning with CoreSessionTracking becuase of an id collision for browser id managers. I assume this is also true of more modern Zope versions. The skins tool will do for most people what they intended to do with TFs, but in a less surprising, and well-documented way (plus you get configurable layering, and concurrent software upgrade migration paths by developing TTW code in another skin than your production application deployment).

I'd second TransparentFolder as a feature request for Zope. They are really useful to structure storage without complicating URLs if you know what you're doing. Of course you have to be careful wrt duplicate ids.

As I recall, they cause horrible (processing) inefficiencies, so they are not likely to be adopted in the base product. The human efficiencies they bring (to us) are substantial. I've been assuming that I'm the only one using TFs, so it's nice to know someone else does. More people to share the load if we ever need to modify the product to handle a change in Zope! Now for my TF usage... It's become *very* common for me to create a Folder such as "proposals" and fill it with other Folders that represent proposals. Then I want tools that act on the proposals (like "PDF_compilation"). It's sooo clean for me to be able to drop a TF named "tools" into "proposals" and then simply call it like this. http://.../blah/proposals/2002001/PDF_compilation I do this all the time. It would be hard for me to go back to a non-TF world. --kyler _______________________________________________ Zope maillist - Zope@zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
