Question on Derived Union

Postby yonedal » Fri May 26, 2017 1:55 pm

Consider the following image from the attached model:
union_ex_im1.JPG


Since the properties Component Kind A and Component Kind B subset the property component which is a Derived Union, I would anticipate that the values in the slot for component in an instance spec of System would be the union of the values for the slots for Component Kind A and Component Kind B.

But, when I go check:

This is not the case. In fact, even when I create a new instance spec of Component Kind A (and name it 4), I'm not even restricted to only using values filling the Component Kind A/Component Kind B slots.

*I find this to be an issue since I haven't added 4 as a value to the Component Kind A slot.*


So what am I missing here? Is there a way to make the tool do this? I'm on MagicDraw 18.1 for this one by the way.
