Which Localizer version are you using? Just to be sure I look the
right source, because it should work.

Yes, and LocalContent objects inherit from ExtensionClass.Base
and from Acquisition.Implicit, not sure which one is the responsible.

When you access a LocalContent object, within Zope, you access to an
acquisition wrapper around the real LocalContent instance, so you need
to use inheritedAttribute. This happens only when you specialize a method
of a parent class and want to call the method you're specializing.

Well, I'm not sure which is the cause, wether extension classes or
acquisition. Anyway, it's needed.


An alternative is to use "im_func", in LocalContent._delLocalProperty,
currently there's:

 LocalContent.inheritedAttribute('_delLocalProperty')(self, id)

you could use this instead:

 LocalPropertyManager._delLocalProperty.im_func(self, id)

First tell me which Localizer version are you using, and if you like,
send me your whole file, maybe this is the quickest.
