I just want to stress that I deleted every prebuilt other data plugins...

My ZClass has only an empty dataskin property sheet.

I have changed the load attribute to id.

This helps a little : with <dtml-var "getItem(REQUEST.id)"> in the
specialist, I get a <HumanClass Instance at xxx> in the HTML code.

But when trying to access any attribute of the instance I get an
authorization error.

I remembered having seen somewhere to put a proxy role on the skinscript =
so I
tried.

With manager, I keep the same authorization error...

With owner or anonymous, I get a NameError on the first name mentioned in=
 the
skinscript...

BTW Has there been a patch for an error I get when using copy or cut butt=
ons
in ZPatterns containers :

Zope Error

           Zope has encountered an error while publishing this resource.

           Error Type: KeyError
           Error Value: manage_tabs
