I got this idea that I might be able to find the classes by getting the
connectionpoint of the associationend-handle, and then looking in the
"connected" GList...
However, it seems that, in that list, only the association object itself is
present (there's only 1 element in the list)...

Here's what I tried:

  orth = &(assoc->orth);
  handle = (orth->handles)[0];
  conpoint = handle->connected_to;
  connObjs = conpoint->connected;
  obj = (Object*) g_list_nth_data(connObjs, 0);

Printing out the address of obj and the address of assoc, showed that both
objects are the same...
Playing around with the indices, I learned that there are 3 handles in the
association (seems logical), and 1 object in the connObjs list...

Am I doing this the wrong way, or is this a bug?

Also, I noticed that, when loading a *.dia file where an association was
connected to UMLClasses, after loading the connection is lost (i.e. when
connected, the end points of the association are red, yet after loading, they
are green again...)

Thanks,

Hans
