[Zope3-Users] Permission problem on adapter

[Dominique Lederer]

hi

i created a trusted adapter on a content object.
then i created a formlib edit page for the ZMI, to be able to edit the
new attributes on the adapted content object. the adapters interface is
correctly rendered to the form.

if i try to edit, an unauthorized error is shown, which i also get, when
i register the user as Site Manager via Grant in the ZMI.
The global admin *can* edit the adapters attributes (the one which is
set globally via ZCML).

i registered the adapter like this:
<adapter factory=".MyClassAnnotations"
         trusted="true"  />

<class class=".MyClassAnnotations" >
    <require
        permission="zope.View"
        interface=".interfaces.IMyClassAnnotations" />
    <require
        permission="zope.ManageContent"
        set_schema=".interfaces.IMyClassAnnotations" />
</class>

i can surpress the error, if i change the set_schema permission to
zope.View. But i think that is just a bad workarround.

what am i missing?
thank you for your help.

traceback is:
