Hello,
as already mentioned in the subject, I would like to know if its possible to
check if an interface is provided by an object inside a tales expression.
I would like to use this in genericsetup/actions.xml as a condition
expression.
Hm, not sure.
Definitively not in the way you would do it from code because
you cannot import the interface in TALES.
I know that in the old days Plone grew the interface tool
(portal_interface or so) to support exactly this for the
old Zope 2-style interface checks but I simply don't know
whether this has been extended to Zope 3 interfaces.
