[Zope-dev] ZPatterns: __getitem__ on a DataSkin instance

Let's say I have a DataSkin-derived ZClass that has the attribute 
"forename" (in a dataskin attribute propertysheet).

If I get an instance of this ZClass from the ZODB (set up to use a 
Folder w/ customizer suppport), I can refer to the "forename" attribute 
using <dtml-var "this()['forename']">.

However, if I get an instance of the same class from a Specialist, 
<dtml-var "this()['forename']"> gives me

    Error Type: AttributeError
    Error Value: __getitem__

Any idea why there's the difference?

Can the latter case be fixed?
