Description rbotero 2008-06-09 16:02:33 UTC 
If you create a model with two related classes A and B, and one navigable relationship from A to B.   You will lose the
relationship if you generate the code and next try to do reverse engineering re-creating the original UML model.
Comment 1 Viktor Lapitski 2008-06-09 22:10:01 UTC 
During Reverse Engineering new elements A and B and an aggregation (as there isn't enough 
info in the java code to distinguish what does an attribute represent - an association 
or an aggregation - an aggregation is created)  was deduced from the source code. They 
replaced the old elements. The old association between the old elements was deleted. 

A merge logic must be added into RE to try to identify and match between relationships 
already existing in the model and ones that are produced by source analysis during RE.
