Well I guess I might come up with the exception proving the rule then ;/
Thanks for confirming there are no known issues.

Let me rephrase, just to avoid any unintended ambiguity: I am trying to
extend content per-instance: the marker interface is assigned to the
instance run-time, right after the instance is created. So this is not
about the usual (?) way, ie. type-wide extension configured statically,
which I've found to work perfectly, as well.

Here's what I did to recreate the issue (ie. initial AT edit form not
including schema extension when portal factory is used):

Using a clean plone 4.2.1 buildout (latest OSX w/python 2.7), empty
egg-cache and a simple zope/plone package with paster, I dropped this
simplified 'extension.py' python module <http://pastebin.com/L95m1h58> and
configure.zcml <http://pastebin.com/xvFtFby5> inside the pkg to hook things
up so that any ATEvents created will be schema-extended as soon as they are
created.

Which again works fine, except that with portal factory, the initial edit
form does not include the added field ("Cost"). Subsequent edit forms again
do, as they should.

I'd appreciate if someone could take a look & try it out.

Thanks,

 Petri
