)

Comment 1 Thuy.d Nguyen 2007-01-17 00:34:05 UTC

According to UML 2.0 Superstructure Specification
(http://www.omg.org/technology/documents/formal/uml.htm),  "An actor can only
have associations to use cases, components, and classes....".  The specs for
Association also mentions that the association end types must be a instance of a
classifier.   Package is not a classifier but a namespace, thus creating an
assocication link between an actor and a package is not supported.

Comment 2 Peter Lam 2007-01-18 00:44:22 UTC

I agree that the spec is correct ;-) 
What is supported beyond the spec is just additional feature of other tools. If
NB UML tool does not support this, this is surely an invalid bug but can be
changed to an enhancement if this feature is requested by users.
