I have a simple model:
EntityOne
EntityTwo
AssociationOne that has EntityOne at the AEnd and EntityTwo at the ZEnd, AND multiplicity of ONE at both ends  (the default).


Create an insance diagram and drag on ONE instance of entityOne, and TWO instance of EntityTwo.


I can then, create (by use of the handles on the diagram):
an instance of an association between one of the EntityTwo instances and teh EntityOne instance.

I can do this startin from EITHER of the two entity insances.

The above is all good.

What is bad is that if I now grab the handle from the EntityTwo (Zend) and drag it onto EntityOne instance, a new assoc is created - this is illegal..

If I grab the handle on the EntityOne instance (AEnd) then The assoc does not get created.

It seems there is some kind of check missing depending on which end of an assoc is used to create the instance.
