No, actually, it is saved (look at the XMI). I investigated this a while ago 
and IIRC the problem was:

- - an AssociationWidgetData object is created
- - it creates a LinePath object
- - loadFromXMI() is called on it, which also calls loadFromXMI on the LinePath 
object
- - an AssociationWidget object is created with the AWD object as parameter
- - the AW sets itself as as association object in the AWD's LinePath object, 
which makes the LinePath object throw away all its state loaded via 
loadFromXMI(), so the defaults are calculated.


Possible solutions: 
- - add another parameter to setAssociation to tell the LinePath to or not to 
throw away its state.
- - call loadFromXMI() after the AssociationWidget object is created and 
setAssociation() is called (not sure if this is feasible).

I ran out of time, so I couldn't finish this :(
