That is the purpose of it - an object-level disable() (and eventual
hide(), possibly).
My reasons for the disable are obvious: Certain objects in my domain
must only be interacted with via actions (promoteMember() to set the
member level and log the action, etc) for certain roles, and it's a bit
tedious putting: String DisableXXX() on every method to runtime
checking.
As for Hide() - how secure is the HTMLviewer against hacking? Can
you probe the entity space by spoofing / loading URLs? I want certain
objects to be completely invisible to certain roles.

Ah - I understand. Spoof object disabling by installing the same facet
on all members. Ugly - the object's disabled() method will be called for
every method in the object.

Thanks - I realised this morning where a breakpoint would be a good
idea - create a disabledXXX() method, and see when *IT* is called,
working upstream of the stacktrace until a suitable loop is found.
BTW: My gut feeling is that hooking into the ObjectMember's
isUsable()/isVisible() Consent in the metamodel makes more sense?
Find where the members are iterated through, and don't bother
checking all members, if the Object-level facet is present?
I'll decide further when I next fire up the IDE - probably tomorrow
evening or Monday.
Thanks for your help.
