I have 3 instances of two sets of classes with a 1 to 1 association between the two. I would like one instance of one class to be associated to another instance of the other class. In other words, 3 1-to-1 associations. I noticed Rhapsody doesn't initialize this association automatically. Even the easy ones with a single instance. Is there a way to define which object is associated with which from within the model, or do I have to do this at initialization within the code?

I'm not sure if I fully understand your problem, but I'll give it a try. Firstly, associations do not initialize/instantiate pointers. They only define them. So drawing an association will define a pointer to an object in your .h file (by default).

In order to instantiate the association, you need to draw a link (green line), between the two objects. The link should automatically match itself up with the association you've already drawn and put in the correct instantiation code. You can double check that the link is matching up correctly by right-clicking on it and then hovering over "Select Association to instantiate". You should then see a check mark next to the association you've drawn.

Thanks. I know that now. I replied to a similar post of mine with the same information.
