Hello Felix,
Hope you have found a way to create association classes in M4 :).
We are actually supporting binary associations only, it is possible to model
N-ary associations with corresponding (empty) association class only.
We can probably add support for them in the same sense as for generalization
sets.
That is, when user initially connects 2 classifiers with association tool,
the default "line" notation is used for binary case (as it is done now),
but drawing the connection with the same tool from 3rd classifier to existing
association replaces it with rhomb-no-class n-ary notation. If you feel it
is what you need, please submit bugzilla for this.
Regards,
Michael
