HTTP PUT uploading to dexterity container folder in site is broken -- returns 404 not found

[Rudd-O]

(Formerly plone/plone.app.dexterity#327 )

Any HTTP PUT (e.g. with WebDAV or with basic curl) to a Dexterity folder receives a response HTTP 404 Not Found, but it's truly the most curious thing, because a PUT of the same file in the parent directory (Plone site) succeeds, and then a PUT of the same file in the current directory succeeds afterwards!

In the following example /manuelamador.name/ is a Plone site, and /manuelamador.name/intranet/ is a Dexterity container (regular Folder) added in the Plone site.

Listing collection `/manuelamador.name/intranet/': succeeded.

This only happens with Dexterity containers. Regular Zope folders work well with HTTP PUT. So do Plone site roots.

Of course, this is bad because MKCOL inside a Plone site root creates a Dexterity container, so any new folders must be created through the ZMI. And using the ZMI is a non starter.

This appears to be caused by a defect in publishTraverse() of plone/dexterity/browser/traversal.py.

I will shortly fix it with a PR.

EDIT: I tried to fix it but I couldn't.

HTTP PUT works on Plone 6, albeit with the caveat in #162 . Please close when Plone 6 is released.
