I've been trying to use the critics as a way of insuring that my model is
complete.  However, when creating use case diagrams I've noticed that the
critics often provide me with feedback that doesn't make sense.

For example, let's say you want to create the following use-cases

Actor -- (Zooming)  --> (Zoom Into Rectangular Selection)
                           --> (Zoom In By Increment)
                           --> (Zoom Out By Increment)

To create the first generalization of Zooming (Zoom Into Rectangular
Selection), I click the Zooming use-case and drag the generalization arrow
at the top of the use-case.  When I release the mouse, the new use case is
created, and I enter it's name directly into the use-case ellipse.

However, when I do this I get feedback telling me that I need to "Add
Associations" to the usecase even though in my estimation I just created the
association that I wanted.

Am I missing something?

Regards,

Mark
